Hi everyone. Suppose I'm using an PWM H-bridge to drive a transformer in order to produce a sinusoid on the other side (to drive an electrostatic ultrasonic transducer). I'd need a filter of some kind, except I'm not entirely sure if I'm supposed to smooth the current (use the inductance of the transformer) or the voltage (RC filter somewhere along the ways) going through the transducer. I'm not sure what's more important.
