摘　　要：设计了一种双正激电路的软开关和预燃电路,分析了它们的工作原理,推导了一些关键技术参数的计 算公式。原边电路的主开关管和副边电路的功率二极管都实现了软开关,减小了开关过程中的能量损耗,减小了电 磁污染。A new sort switch topology of two-switch forward converter and xenon-lamp simmer circuit was designed, the principle of their main circuit was analyzed and some key parameters were calculated. The analysis demonstrates that soft-switching in the switches of the primary circuit and in the diodes of the secondary is realized, the switching loss and EMI are also reduced.
