Re: Circuit design help - power supply - Non FIRST
Gdeaver has the right idea - you could make an resistor- capacitor or resistor inductor filter circuit that would turn a square wave into something approaching a sinewave.
For the current levels you want the inductor or capacitor would have to be very large. If you use an inductor you have to make sure it cant spike negative when the pulse is shut off. This is normally accomplished with clamping diodes.
