Class-E zero-voltage-switching and zero-current-switching rectifiers

Abstract

A number of class-E, half-wave and full-wave, zero-voltage-switching (low dv/dt), zero-current-switching (low di/dt), and mixed-mode rectifiers are introduced and verified experimentally. The rectifiers are derived from conventional rectifiers by adding reactive components. New conventional rectifiers are also introduced and presented in a systematic manner. The principle of class-E rectifier operation is explained using current and voltage waveforms. The class-E rectifiers offer a means of rectification suitable for high-frequency applications, e.g. in resonant DC/DC power converters. A general approach to the synthesis of resonant DC/DC converters is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
