Class E zero-voltage-switching rectifier with a series capacitor

Abstract

A circuit of a class E rectifier with a series capacitor is derived from a class E amplifier, using the symmetry between a DC-to-AC inverter and a rectifier. The principle of the circuit's operation is described and verified experimentally. Since the rectifier diode turns on and off at zero voltage, the switching losses are considerably reduced. In addition, the rectifier diode turns off at zero current, reducing the effect of the reverse-recovery time. The rectifier can be used in high-frequency high-efficiency resonant DC/DC power converters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
