Abstract :
A simple form of a buck-derived interleaved four-quadrant PWM power conversion stage results in a doubling of the output ripple frequency while greatly reducing the ripple current amplitude. Shoot-through currents are reduced to low dI/dt events that are readily controlled allowing zero deadtime operation
