Electric motors don’t like pulsed currents but rather use a smoothed wave form, either an analog wave or a wave like digital form such as pulse width modulation (PWM). AC from the grid is a wave form in both single or three phase. Capacitors can be used to filter out the 200 Hz pulses to create a flat DC current, then be converted to AC by PWM at whatever the local frequency is, 50 or 60Hz.
