摘要：

A family of Class-dc/dc power converters is introduced. Analysis and design are presented and experimentally verified. The converters are composed of Class-E inverters and Class-E rectifiers. Zero-voltage switching (with low dv/dt) of the transistor and zero-current switching (with low di/dt) of the rectifier diode reduce switching losses in both stages of the converters, making them especially suitable for high-frequency operation. Because of the high loaded quality factor of the resonant circuit, the range of frequency required for output-voltage regulation was as narrow as 5.46 percent for load resistances from a full load of 100 Ω to an open circuit. The full-load overall efficiency was 80.36 percent at 1 MHz. The new converters can also operate at a fixed frequency if synchronous rectifiers are applied. The reduction of Class-E2 converters to lower order converters is presented. Many new topologies of “multiresonant” converters are created in this way. The Class-E2 converters can be utilized to build highly efficient high-power-density switching power supplies. © 1990 IEEE
