摘要

高开关频率与软整流技术相结合是开关变换器的发展趋势。根据这一趋势，本文提出了一系列的PWM软单开关变换器，它只有一个有源开关，能够以脉冲宽度调制的方式进行软开关工作，没有高电压和电流应力。此外，这种变换器可以在高开关频率下工作，适用于大范围的负载。为了说明这些新型变换器的工作原理，进行了详细的研究，包括仿真和实验测试。所得结果证明了这些新型变换器的有效性。

PWM soft-single-switched converters without high voltage and current stresses

High switching frequency associated with soft commutation techniques is a trend in switching converters. Following this trend, this paper presents a family of PWM soft-single-switched converters which, having only a single active switch, are able to operate with soft switching in a pulse width modulation way without high voltage and current stresses. In addition such converters can work at high switching frequencies for a wide range of load. In order to illustrate the operating principle of these new converters a detailed study, including simulations and experimental tests is carried out. The validity of these new converters is guaranteed by the obtained results.
