Hi there all.
I want to simulate switching amplifiers in multilevel mode, however the simulation go well, but implement a gate driver is not.
Is there someone here who can tell me hoe to implement a mosfet gate driver in a multilevel flying capacitor and a cascaded version
of inverter system, I want to see what it does with audio when use that multilevel systems, special the 5 or higher levels, the three level]
does work fine, distortion is in the 0.002 level on 3 amps out in 8 ohms self oscillating.
The cascaded version has flying supply's for every level, driving these I think needs insulated drivers and special bootstrap? and the flying
version has just one voltage supply or differential like normal, but the levels are between the mosfets, so there are different voltage levels then,
bootstrapping is here also difficult, of need cascaded bootstraps.
I am just some curious, I am a high end man so this switching stuff is quite new for me. I now there are chips who has multilevels, but these are
made with shifted triangles and one 90 degree shifter half btl from audio.
thanks for help.
