【摘要】 文中分析了并联谐振变换器(PRC)电路的拓扑结构及工作原理,提出了在软开关条件下实现电源输出连续可调节的方案,并通过一种实用的交流分析法分析了PRC在CCM工作模式下实现方案的可行性。最后的PSPICE以及Matlab/Simulink仿真结果表明该变换器具有输出连续可调节范围大、软开关、效率高等优点。更多还原

【Abstract】 The circuit topology and operating principle of Parallel Resonant Converter (PRC) are analyzed in this paper. An idea of continuous-adjustable output soft-switching PRC is presented and its feasibility also analyzed by using an useful AC analysis technique. The PSPICE and Matlab/Simulink Simulation results prove that this kind of converter has the virtue of wide-range output, soft-switching , high-efficiency etc.更多还原
