摘要
采用硬开关对称式隔离半桥拓扑设计出输入输出功率2000W高压DC／DC开关电源。详细分析了电路工作的波形，尤其是占空比丢失的相关细节波形，为半桥电路设计者分析电路提供参考。最后的仿真实验，证明了分析的正确性。
Hard-switching half-bridge topologies is used to design isolated switching power supply, which input voltage is 600V and output voltage is 250V. The Switching power supply power is 2000W. To provide a reference for the analysis of the circuit designer.This paper emphatically analyzed waveform of the circuit , Especially the relevant details of the duty cycle loss waveform.Finally, simulation experiments to prove the correctness of the analysis.
