I read several comments and realized I'm part of the ElectrArc240 fan club that's super impressed by the depth of your knowledge!

Wow!! Your depth of knowledge and skill set is that of someone twice your age. Assuming you are studying electronics at uni, then I think it's fair to say that the first class honours already has your name on it. Another fascinating video, thank you.

Great stuff mate !^.^! btw, 99.99% of the time you want an E-stop button and circuit to be a normally closed circuit. that way if any part breaks or any wire comes loose then the product stops, making it so you must fix the loop so it ACTUALLY WORKs when you do actually need it

Please continue uploading great videos

You are a very knowledgeable person, your videos contain so much information, I am amazed. I only just learned about the difference between BLDC & PMSM only a few days ago, I mean the real thing, not the superficial crap of most KZfaq videos when they refer to both as only Brush less motors! Distinguishing between the Trapezoidal waveform and Pure 3 phase sinusoidal waveform to drive these motors, the sinusoidal which is 100% efficient. I guess the next step is to supply the inverter with power from the mains but going through an home-built PFC (Power Factor Correction) circuit. People would state that its "The rise of the Machines" era, but I think its "Rise of the Inverters" with EVs, AI coming afterwards!

I was waiting for this one... Love it.

Love to see you back 👍, another great video!

Wow excellent 👌👌

Formula Student, ah okay sounds familiar to me 🙂 So great 🙂

great stuff!

Your audio is noisy because your clock frequency is only 29kHz. You probably want to increase it up to 44.1kHz or 48kHz depending on your audio sampling rate.

For gate drive I would've swapped the position of the cap bank and the Fets. Having your gate drive paths being that long is not always a good idea. Swapping the caps and Fets positions would make your gate drive paths much shorter. Even with it come that way your high current tracks would still be able to be extremely short as well. There's a lot of emi going to be generated which can cause issues with your gates. You can also place decoupling on your main chip directly on the headers on the top of the board, that would work very well.

Great video.

@20:20 To be safe use for each ouput a BZV55C16 voltage limiter ISA only D6 *or* place a high value resister parallel with the capacitor C12 and C14 (100k or so) else there is a possible voltage shift between +V and -V

👍👍

What a nice project. I am considering about doing something like that!!

Question... you've used 3 half H-bridges to make a 3 phase output... could you just use 2 half H-bridges using these drivers to run a brushed DC motor?

Can you also show some insights on single phase then 3 phase Solar inverter?

Awesome project to begin with! Really love the symmetry of PCB. You must have put a lot of hours into it. One question: I am also building a frequency converter and was wondering how you got that lookup table in the software with the third harmonics (the modulated wave that looks like a saddle-like shape). Did you use some kind of calculator for the lookup table? I would really like it to implement this in my converter. Thank you in advance!

you are a very man. Can to provide the PLC code for PLC chip you use, please?
