摘　　要：分析研究了一种新颖的单级高频链逆变电源的电路拓扑、控制策略、稳态原理特性、关键电路参数设计准则。该逆变电源功率电路是由两个正激式双向直流变换器输入端并联、输出端反向串联且共用一个输入、输出滤波器。实验结果表明,该逆变电源具有单级功率变换、高频电气隔离、电路拓扑简洁、输出电压波形质量高、负载适应能力强等优点。The circuit topology,control strategy,steady-state principle characteristics and key circuit parameter design criteria of a novel single-stage high-frequency chain inverter power supply were analyzed and studied in this paper. The inverter power circuit is paralleled by two positive two-way DC converter inputs,the output side in reverse series and shares an input and output filter. The experimental results show that the inverter power supply has the advantages of single-stage power transformation,highfrequency electrical isolation,simple circuit topology,high quality of output voltage waveform and strong load adaptability.
