We are trying to drive our full bridge inverter with a mosfet driver (HIP4082) connected to a SG3525 PWM chip. For some reason I think the frequency @ 60 Hz coming out of the Sg3525 is too low and the sync pin (Sg3525) may be acting differently then we want it to. We are trying to produce a 60 HZ sine wave. Any possible suggestions that can help me?
