Abstract
A control circuit includes a controller that provides a master PWM signal indicative of a difference between a predetermined setpoint and a process signal. The control circuit also includes a PWM splitter circuit that receives the master PWM signal and provides a first PWM signal for a first switch and a second PWM signal for a second switch. The first PWM signal corresponds to a first portion of the master PWM signal and the second PWM signal corresponds to a second portion of the master PWM signal.
