CLASS E ZERO-VOLTAGE-SWITCHING AND ZERO-CURRENT-SWITCHING RECTIFIERS

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. The rectifiers are presented in a systematic manner. The principle of the Class E rectifier operation is explained using current and voltage waveforms. The Class E rectifiers offer a new means of rectification suitabile for high-frequency applications, e.g., in resonant dc/dc power converters. A new general approach to synthesis of resonant dc/dc converters is presented. © 1990 IEEE
