Why do we talk so much about motor efficiency and so little about inverter losses in EVs?
I've been spending more time looking at EV motor controllers, and one thing that gets overlooked in general EV discussions is how much the inverter contributes to overall drivetrain efficiency.
Even with a good motor, you've still got switching losses, conduction losses, dead-time effects and thermal limitations in the controller.
And the operating point matters. A controller that's efficient under one load condition isn't necessarily operating at its best during repeated low-speed acceleration or high-current operation.
What's interesting is the trade-off between higher switching frequencies, current ripple, audible noise and heat.
SiC devices can improve some of those trade-offs, but cost and system design still matter.
For anyone who's worked on motor drives or inverter design, which tends to be the bigger challenge in practice: reducing switching losses, managing thermal performance or getting the control strategy right?
I'm particularly interested in how those priorities change between low-cost two-wheelers and larger EV powertrains.

[career guidance] is it ok to do internship in different industries?
I'm a third-year Electrical Engineering student, and I just got offered a co-op position from an MEP consulting services company. I truly want to try out what different industries are like because I interned as a design engineer at an aerospace company last summer, and I learnt a lot about analog design and stuff. However, I kinda want to get the full experience of what it feels like when working in different industries before I graduate so I don't regret when just going all in for just one specific industry. That being said, my boss from the company I interned at last summer also offered me a spring part-time job (circuit design intern at an aerospace company). What would your advice be to me if I am just dumb for burning the bridge with the previous employer, or is it ok to try out different industries?

Jobs/Careers Job Assessment - Disability Accommodations
Hello,
For an engineering job I’m applying to, they want me to complete a timed, online assessment. However, I have several disabilities for which I would require accommodations on the test (when I was in school, I received extra time and other aids).
Should I inform the hiring manager of this?
On the one hand, I’m leery about disclosing disability status, since I know they’re not SUPPOSED to discriminate on that basis, but I absolutely don’t trust this in the current job market. Especially since this would be my first full-time engineering job.
On the other, accommodations would improve my chances of success.
Have any other disabled engineers been in this situation while job searching? What did you end up doing?
EDIT: for context, I’m in the US. Employers are generally prohibited from disability-based hiring discrimination, and must make “reasonable accommodations,” but those protections don’t seem very strong right now

Jobs/Careers Qorvo/Skyworks Vs. Raytheon
Junior EE student here. I got both internship offers from both companies, but I couldn't decide which one to choose. Qorvo would be a test/validation role while Raytheon would be antenna work. Both roles seem interesting to me. Would it be a good idea to try commercial semiconductors first then maybe transition to defense in the future? Or would it be better to just go straight to defense.
I heard that work in commercial semiconductor can be fast-paced and lucrative while defense work is slow yet stable. I'm very indecisive at the moment.
I appreciate anyone's time and advice.

Troubleshooting Would this neutral-switching circuit be original or did someone rewire it incorrectly?
I bought this non-working Naomoto HYS-5 gravity-feed steam iron online and wanted to get it working again. I’ve tested the wire paths and it looks like it just needs a new thermal fuse. Before plugging it in though, I want to make sure it’s wired correctly.
The current wiring has neutral going to the on/off switch and hot going directly to the heating element and steam button, meaning even with the thermostat set to zero, the steam button and heating element are still getting power?
I’d taken it apart which is why terminals are disconnected but each one is touching its corresponding terminal. The schematic is ai generated, so a little wonky, but represents the wiring as it is now.

Education Should I switch from Finance to Electrical Engineering?
Hey guys, I’m a freshman finance student thinking about switching to EE next semester. I think I do find finance and economics interesting but I would just like to learn about how phones and electronics work. I’ve wanted to go into engineering for a while but I’ve always been worried about the difficulty of it. One reason I chose Finance when applying to college rather than engineering is because I thought I wanted to have time going out partying and clubbing. I did do some parting and clubbing thus far, yes it was fun but at the same time it wasn’t all that to be honest. Like, I enjoy it but not as much as I expected, I’d like to do it maybe once every week or two but not more often than that. Also, I am somewhat introverted and have social anxiety and I fear that would cause issues in a finance career.
Another reason I was scared of doing engineering was because I did really poorly in high school calculus. I’ve been taking business calc this year and I’m doing pretty decent so I’m less scared of calculus. I do have issues with time management and managing stress though. Also, I do value free time, I’d ideally like at least an hour or two of free time for myself each day.
I want to do electrical engineering but I’m just scared that it’ll be too difficult even though I find it to be a “cooler” thing to study. I wonder if I’m overly anxious and should just study engineering since I feel more compelled to.

Career change at the age of 40
I am 36 years old and considering pursuing a Bachelor’s degree in Engineering, specialising in Mechatronics, Mechanical, or Electrical Engineering, in Germany as an international student. If I receive an offer from a university of applied sciences, I may take out a student loan to finance my education.
My biggest concern is whether I will face age discrimination when looking for an engineering job after graduating at around 40, and how significantly it could affect my chances of finding employment.
I have been considering this career change for some time because I have struggled to progress in my current career and have been working in the same position for the past 11 years. I see engineering as an opportunity to start a new career, develop practical technical skills, and improve my long-term prospects. However, I am also aware of the financial risks involved in taking out a student loan and the uncertainty of securing a job after graduation.
If transitioning into engineering does not work out, my backup plan is to pursue an online Bachelor’s degree in Data Science and AI from IIT Guwahati (IITG) through Coursera while continuing to work full-time. Since IITG is a reputed institution and the programme is relatively affordable, I hope that earning this degree could strengthen my qualifications and improve my chances of career advancement in my current field.
Given my age, professional background, financial situation, and career goals, which path would be the more sensible choice: pursuing an engineering degree in Germany or studying Data Science and AI online while continuing to work in the UAE? (I am more inclined towards doing an engineering degree)

Your Opinion on an Educational Channel
I have been thinking about starting some sort of educational channel for a while now.
Quick context, I design industrial control panels. I am thinking of creating in-depth videos designed to make people confident about topics such as:
- panel load calcs
- motor controls and sizing
- inside panel layouts
- PLC racks
- wiring methods and insulation
- picking what parts to use
- conduit sizing
- wire duct fill
- transmitters
- reading customer specs
- etc.
Topics around things I have seen instead of the usual "this is how a relay works". Most of my Googling and YouTubing brought up videos for cool Arduino projects, AutoCAD playlists, and third-party panel building services. Not a ton that a designer might find useful day-to-day.
Is an educational channel with that idea something folks would potentially like to see, or would I be wasting my time?
P.S.: I read all the rules before posting as best I could. If this post still needs to be taken down, just give me a slap on the wrist instead of the the Ban-Hammer and tell me what I did wrong and should avoid next time. Just trying to create something instead of constantly consuming.

Jobs/Careers Is a Utility Engineer role at an EV battery plant a good fit for an EE grad focused on Power?
Hi everyone,
I am a recent graduate with a Bachelor of Engineering in Electrical Engineering, and I just received a job offer for a Utility Engineer position at an EV battery cell manufacturing plant.
I’m trying to figure out if this role is a good fit for my background and interests. During school, I didn't focus too heavily on one specific area, but the field I felt most comfortable and familiar with was power systems. On the flip side, I had a pretty difficult time navigating the electronics and software/programming sides of the curriculum.
My concern is whether a Utility Engineer role in a manufacturing setting is actually relevant to an electrical engineering path. From what I understand, utility engineering in standard manufacturing tends to lean heavily toward the mechanical side (handling HVAC systems, chilled water loops, dry room environmental controls, etc.). However, since this is a battery cell plant, I know there will be a massive electrical infrastructure, including huge in-house substations, switchgears, and complex power distribution networks.
Additionally, I have zero co-op or internship experience, so I am not very familiar with how day-to-day operations work in industry. My current understanding is that a factory that is already running smoothly doesn't tend to have major engineering "problems" to solve and mostly just needs routine maintenance. Is this true, and is this role still a good way to actually learn, build a engineering career, and get valuable experience? Is facilities/utility engineering in this sector a good career choice for the future?
For those with experience in the manufacturing or EV sectors:
Does an electrical utility engineer in this type of plant actually get to work hands-on with the high-voltage power systems and substations?
Or does the day-to-day work still end up being mostly mechanical and HVAC-focused?
Would this be a solid starting point for someone looking to build a career in power engineering, while trying to avoid heavy coding and electronics?
Given my lack of co-op experience, will a running plant provide enough deep learning opportunities, or will it just be basic maintenance monitoring?
I would love to hear your insights or any experiences you've had with facilities/utility engineering in the EV or battery space. Thanks!

Education K- rated Transformer
K-factor: this is a derating factor for a standard transformer used to supply non-linear loads, so that the total loss on harmonic load does not exceed the fundamental design loss of the transformer.
What does it exactly mean by "fundamental design loss"? Is it the full load loss of the transformer under fundamental frequency; If yes, then how come the total loss on harmonic loads could be less than the "full load loss of the transformer under fundamental frequency + harmonic load loss"?

Is there more to electrical engineering?
Current a 2nd year grad in EE. Did an electronics apprenticeship that turned out to be a shitty manufacturing company with no good prospects. Got my degree paid for but had no technical experience. Moved into a grad job at a consultancy and so far it's just report, reports, reports. I wanted to be a design engineer but there just seems to be no demand for design engineers. Now I feel like I'm stuck in a very technical role doing earthing, power systems studies and reports. Did I pick wrong the wrong field? I'm very hand ons and creative doing art, design & technology, wood working at school. Where's the practical creative side of EE?

Hey guys, as a fellow Electrical Engineering student in Europe, I am seeking some information about the market, as this year I need to choose between an internship in Microelectronics or Power Systems.
I prefer Microelectronics, but I don't want to specialize in a field that is TOO competitive or less in demand. I know for a fact that Power Systems is one of the most in-demand industries, using my country as an example.
In Portugal, the market is roughly 50% Power Systems and only about 10% Microelectronics, but working in another country is always an option.

Just a quick question
Im a call center and we use poly headsets where the volume control is away from the ear piece and is powered by plugging the USB c to a computer. My coworker said that her volume control was heating up and was causing for the ear pieces to heat up... honestly, I feel like she's lying so she can avoid taking calls. Can that volume part cause shorts to heat up... is the draw of electricity even enough given that there is no battery on it, processor, nano cell etc. The exact model is in the picture.

Jobs/Careers Meta EE Intern Technical Interviews
metacareers.comI’m a Junior ECE student and reached the technical interview stage at Meta, which is 2 45-min interviews with engineers: one with a Senior Engineer (I believe) and the other with an Engineering Manager. My interviews are this week.
I was wondering if anybody knows what kinds of questions they’ll ask? I tried my best to brush up on communication protocols but I’m not sure how much the interview will emphasize technical knowledge versus discussing my projects and leadership. Also, will the manager ask different questions from the senior engineer?
Also, do they ask any coding questions? My recruiter said the technical interviews “typically cover a combination of hardware concepts and coding problems,” but the job description doesn’t list anything coding-related under the Required Qualifications, only Preferred. (2 people have looked at it and told me they don’t think they will make me code).
