About 11:49 segment showing "Current Measurement" item: i'd like to read "Allegro ACS733" right under that function bloc, literally, because of its specific features (3.3 Volts, electrical isolation, 1 fast comparator/digital output, 1 near-distortion-free DC~50 KHz analog output)... So, as a suggestion my wish is to see some future version applying it all to portable/pocket induction drivers capable of "injecting" ~100 Joules "Heat Charges" into a 0.75 g "susceptor" within no more than 2 ~ 3 seconds on a pair of sturdy 3.7 Volts e-Cig batteries. Right now DiY solutions involve bulky RF Chokes which should get conveniently dealt with just by changing of topology, as illustrated by Infineon's MA12070 Class-D Digital Audio power amplifier for example, since it requires no large inductors...
I was simulating three level for audio, I use flying capacitor. However despite I use natural balancing it do not stay on zero volts, it just walk to positive and negative side, or when using a other mosfet driver i get that it go overlap, I use feedback for the audio system. I think differences in delay between mosfets is cause, but when set dead time bigger it stays nicely around 0 volts, I use symmetrical voltages. Is there a fault maybe with the dead times? I get als in time a bad suppression of the fundamental carrier so I think als to the delays, maybe bad models in ltspice. I can go try lossless parts in sim, like you do in Matlab.. thanks in advance.
Yes just keep in mind for low to medium voltage application give the capacitor value 4.7*e-3 F.For further explanation I will cover a separate video on that.
@@RanitSengupta what if the voltage supply is 400 -500 and switching frequency is 10k Hz can I still use 4.7*e-3 for dc bus capacitor and flying capacitor?
Sir, please explain more on pdpwm in next videos.. Excellent work.. 🙏🙏
Sir please explain for a 7 level flying capacitor multilevel inverter on how to make the PWM pulses
PWM generation is same as 3 level,5 level PDPWM.

Hi sir, thanks for the vid! But how did u calculate the value for main dc bus capacitor and the flying capacitor?
Yes just keep in mind for low to medium voltage application give the capacitor value 4.7*e-3 F.For further explanation I will cover a separate video on that.
