介绍了一类E类/sup 2类/ DC/DC功率变换器。介绍了它们的分析和设计，并进行了实验验证。变换器由E类逆变器和E类整流器组成。晶体管的零电压开关（低dv/dt）和整流二极管的零电流开关（低di/dt）降低了转换器两级的开关损耗，使其特别适合高频工作。由于谐振电路的高负载品质因数，对于从100 Ω的满载到开路的负载电阻，输出电压调节所需的频率范围窄至5.46%。在1 MHz时，满载总效率为80.36%。如果应用同步整流器，则转换器也可以在固定频率下操作。提出了E类/sup 2/变换器降阶的方法。许多多谐振转换器拓扑都是以这种方式创建的。E/sup 2/类转换器可用于构建高效、高功率密度的开关电源。>
A family of class-E/sup 2/ DC/DC power converters is introduced. Their 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 is as narrow as 5.46% for load resistances from a full load of 100 Omega to an open circuit. The full-load overall efficiency is 80.36% at 1 MHz. The converters can also operate at a fixed frequency if synchronous rectifiers are applied. The reduction of class-E/sup 2/ converters to lower order converters is presented. Many multiresonant converter topologies are created in this way. The class-E/sup 2/ converters can be utilized to build highly efficient high-power-density switching power supplies. >
