Abstract :
A simple form of a buck-derived interleaved four-quadrant pulsewidth modulation (PWM) power stage results in a doubling of the output ripple frequency while greatly reducing the ripple current amplitude. Shootthrough currents are reduced to low dI/dt events that are readily controlled, allowing zero dead-time operation
