--- Quote from: j_omega on July 15, 2022, 09:36:53 pm --- I did some more looking at the pro-audio market and found some nice offerings from Crown, QSC, Yamaha, and Behringer. For this purpose, does the class of amplifier matter (AB vs D)? I can find some name-brand high-power AB amps on eBay for great prices. --- End quote --- If you choose a class-D amplifier, you will most likely have some switching ripple on your output signal. It could be annoying when measuring with a scope for instance. |

I'm mostly interested in a three-phase PWM generator. I will be grateful for any help. |

Hi, Source is a selfbuild three phase generator and "of course" I can“t tell anything about it. But you can try to get a cheap VFD and do some reverse engineering on it, most VFD got three phase outputs... |
