Does anyone on the forum have class d amplifier design experience. I am getting ringing on the output sine wave of my class d amplifier. This issue affects both channels at output voltage levels greater than 50V peak to peak. The amplifier does not clip until 65V peak to peak (run from a 36V supply).
I suspect the issue is due to a silly mistake in my pcb layout. My output inductors for the low pass filter are WURTH ELEKTRONIK 7443642200 Surface Mount Power Inductor, WE-HCF Series, 22 µH, 30 A, 18 A, Shielded, 2400 µohm. Low pass filter capacitors are PET film Kemet 600V.
