I was busy to wim a flying cap multilevel class d, I did disciver after some changes in modulation system, like not four but two triangle carriers for 6 level, dit give this open loop respons, that is really low, I had bat common mode problem and solve that with this idea of carriers who have two 90 degree appart one, and one inverted audio channel give the 5 level.
With air coil low pass, I can get maybe nice sound amp.
in pic are 1 Khz 20 Khz and 40 khz and the mudulation pulses.
I do now now precise what to do with a flying cap multilevel pwm what concerns deadtimes, on sim I have no shoottroughs.
