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.

Thank you!!

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 KZread 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!

Woohoo go inverters, love them! Yeah I was planning a PFC video but still haven’t got round to it, will probably be a video in the direct current control series.

Please continue uploading great videos

great stuff!

Wow excellent 👌👌

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

Love to see you back 👍, another great video!

Love to see you back 👍, another great comment!

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.

With better FETs I definitely plan on that

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

Hi, Mr. I was wondering if it is possible you could share the schematics of that project. I would like to understand better and to do it by myself 🙌🏼

It’s a very standard inverter, nothing special. 3x MOSFET half bridges, each FET has an optically isolated gate drive with an isolated DCDC. They’re all controlled from a microcontroller.

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!

Thanks! I generated the saddle-like wave using a python script I made. I think I did a very over complicated method so as probably not the best to advise haha!

​@@electrarc240 Thanks for the reply. In the meantime I have also made a Python program that generates a lookup table with a third harmonic in it. Fourier comes in handy again.
