提出了一种在 DCM 下运行的软开关 AC-DC 转换器单元。介绍并分析了转换器的工作原理和各种工作区间。通过一个 1 kW 交流-直流转换器单元的设计示例说明了设计过程，该单元在 165 至 265 V rms 公用线路上运行并以 100 kHz 开关。包括损失计算。根据设计实例，使用 SPICE 仿真验证转换器的操作和性能。介绍了采用曲速 IGBT 设计的转换器获得的详细实验结果。该转换器具有低线电流 THD，测量效率约为 95%，将用作多相 5 kW 转换器的单元。
A soft-switched AC-to-DC converter cell operating in DCM is proposed. Operating principle and various operating intervals of the converter are presented and analyzed. Design procedure is illustrated with a design example of a 1 kW AC-to-DC converter cell operating on a 165 to 265 V rms utility-line and switching at 100 kHz. Loss calculations are included. Based on the design example, operation and performance of the converter is verified using SPICE simulations. Detailed experimental results obtained for the designed converter employing warp-speed IGBTs are presented. This converter has low line-current THD and has a measured efficiency of about 95% and will be used as cells of a multi-phase 5 kW converter.
