would capacitor banks surfice for 500w motor? also now looking in the old inverter there are 2 modules: switcher and spwm. spwm is egs002 which runs 23khz, too high for igbt, but has a 0-400hz variable function so i read. if i swap the crystal to a lower frequency and crank up the apparant frequency to 400hz to even out at 50 i might be able to utilise this module if its not kaput. the module has dead time setings too, but i dont know how adjusting the clock will affect these.
