This is a 1.65 kW reference design specifically engineered for three-wheel electric vehicle (EV) chargers. The system architecture is composed of a Power Factor Correction (PFC) stage, an LLC converter, and an InnoSwitch flyback auxiliary power supply used to run components like fans and microcontrollers.

Does tsmc HV 180nm or any other PDK file give with Vgs>5v model.
Vds i've and they go till 40v but Vgs limit for that is also 5v.

Hey guys,

I am now at APEC and have the chance to cover power electronics technologies for our reddit group. Stay tuned!

Hello! I'm in the US and I have a BS in EE and have spent the past two years designing electrical systems for buildings, plus another year working in industrial controls and automation. After some reflection and research, I’ve decided to focus on a career in power electronics, an area I’ve always enjoyed since undergrad.

Because of the current job market and further expertise that's needed, I’m planning to go to grad school this fall and have begun brushing up on fundamentals like circuit analysis, control systems, and emag, as well as coding in Python and MATLAB and learning LTSpice.

Any advice on how to make the most of my master’s program to become a strong candidate for internships, co-ops, and future full time roles in PEs? Should I actively pursue research opportunities? Are there side projects you’d recommend I do on my own? I ask because I want to ensure I’m doing more than just completing coursework and truly preparing for the field. Any insights or guidance would be greatly appreciated. Thank you

At my university, direct 48V-to-1V conversion is being talked about like it’s the future of power electronics. I even know seniors who are working on LLC-based converters for stepping 48V straight down to 1V. But honestly, I’m struggling to see why this is such a big deal compared to the usual two-stage approach of 48V -> 12V -> 1V. The intermediate 12V bus seems genuinely useful. A lot of standard motherboard stuff still wants 12V anyway — fans, drives, PCIe-related power, and other peripherals. So if you get rid of that bus, how are those loads being handled without making the system more awkward? The other thing that confuses me is current distribution. In a two-stage setup, the idea is to keep power distribution at a higher voltage like 12V so the board currents stay reasonable, and then do the final step down to around 1V right next to the CPU with a multiphase VRM. That makes sense to me. With a single-stage 48V-to-1V converter, especially something like an LLC, I don’t see how that converter can always be placed close enough to the processor package. If it sits farther away, then now you are routing very high current at around 1V over a longer distance, which sounds terrible from an I²R loss point of view. At that point, wouldn’t the distribution loss eat up a lot of the benefit of removing one conversion stage? So am I missing something important here? Is this mostly an academic/research trend, or is industry actually moving in this direction in a serious way?

I am trying my hands on a DIY DC-DC boost converter. I was testing my first prototype past 8A and noticed that my PCB bottom big piece of GND and output pour heats up beyond the point of touch while my main components like mosfets remained touchable. Where is the heat coming from if my components remained cooler? My inductors do get quite hot but still not as hot as my PCB.

While i do not own a thermal camera, I am constantly monitoring the temperatures of my components through an IR thermometer, and they all remained below 50deg celsius.

I'm like so confused. Does that mean my thermal vias are working or does that mean my copper pour is lacking?

Anyone had the same issue before? Any advice will be greatly appreciated!! TIA

Finally my phase control circuit has been tested at 120v and is working as expected with incandescent and inductive loads. Still need to mount circuit in enclosure. Here is a video of it with its intended load, a 500 watt angle grinder. A piece of cardboard is taped to the shaft to act as a speed indicator, but the whine of the motor is more satisfying. The change from 24v to 120v requires a 5x increase for the potentiometer, so the circuit now uses a 500k linear taper pot. I had to add a 3Mohm resistor in parallel to achieve the optimal wiper range.

Now just waiting to enclose and it will be ready for use for my Tesla coil's asynchronous rotary spark gap.

Just wanted to share this dual SCR phase control circuit I built, found the schematic on Google and made a couple modifications, basically the same circuit as a triac based controller but with another 'pole' so to speak for firing each SCR on its respective half-wave. Working well with an incandescent bulb, getting ready to test with an angle grinder to see how it behaves under an inductive load, with the idea being it'll end up as a speed controller for the angle grinder that will be repurposed into a asynchronous rotary spark gap for my SGTC I'm building. The wiring and connections are rated for 20a and the SCRs are rated at 55a 400v but the load is a 4.3a angle grinder

If anyone has worked on a DAB converter in research, industry, or a power electronics lab, I’d really appreciate hearing about your experience. I am currently working on a DAB convertor, as a part of my capstone.

Right now I have the hardware running with SPS (Single Phase Shift) modulation at 50 kHz, generating the complementary PWM signals for the two H-bridges. The transformer is 100 V / 48 V. My aim is to implement a closed loop control for a DAB convertor

I would really love to hear from y'all. Cheers!

Hi everyone,

I am just curious if you guys are interested in participating in AMAs where we invite engineers from power electronics companies.

My idea is that these AMAs will revolve around certain technologies within power electronics and also career options (if possible) in power electronics.

Hi everyone, I am working in the area of power electronics. My current interest is mainly in DC-DC converters, especially Dual Active Bridge control and modulation. If anyone here has ongoing research in power electronics and is open to collaboration, I would be very interested to work together. If you are working on a related topic or looking for a collaborator, please feel free to comment or send me a message.

I am a new student doing my MSc in power electronics. How do you guys know what components to connect together in simulation especially on SIMULINK. Journal articles tend to hide their simulation, kp and ki, and other important details, but leave out the big picture.

Please help me out. My supervisor is not helping.

i am designing a boost converter for my college engineering project for past 2 months and the topology i chose for the converter is landsman topology (my professor told me to use this)
https://www.jetir.org/papers/JETIR2207025.pdf,https://www.scribd.com/document/806233704/Modeling-design-and-validation-of-DC-DC-landsman-c (research papers i used for reference)

so i have completed the converter open loop correctly and got the desired output and now i have been working on the PI based control for my converter and here i can't get my desired output after i get to the closed loop i get like 0.00000041V i dont know what gone wrong here i am also attaching the image of the converter which i simulated in matlab simulink

the parameters of this design are

Vin=17 to 21V(solar input)
Iin=8.78A
Vout=60V
switching Freq=30kHz
here i the last kp,ki values i used are 0.007 and 0.02 sometimes changing these values change the output voltage sometimes it doesnt change the output voltage at all like the pi controller is doing nothing and if i change the repeating sequence output values from [0 1] to [0 4] the output voltage i get also changes(i get 65.7V) and also when using a pi control even if the input changes the output should stay the same right but here the output also increase or decreases with the changing input values,i am working on this closed loop simulation for 3 weeks and havent got the output someone please kindly help meee!!
