摘　　要：采用饱和电感式全桥谐振软开关技术,设计了逆变电路、中频变压器和输出滤波电感组合电路。采用仿真分析的方法,研究开关管的损耗及输出负载波形。通过仿真分析可知,软开关技术能够提高效率,节约能源;中频变压器和滤波电感的组合使得输出负载波形平滑稳定。With the technology of full-bridge resonant soft switching of saturation inductance type,the combinational circuit of inverter circuit,intermediate-frequency transformer and output filter inductor is designed. The wastage of switch tubes and waveform of output load are researched by simulation analysis. It is showed that soft switching technology can improve efficiency and save energy;the combinational circuit makes the waveform smooth and steady.
