摘要
在开关电源设计中,输出电压控制是高性能开关电源必须解决的关键问题。利用MC33262作为临界电流传导模式控制器的特性,设计了一个E2类软开关DC/DC变换器,并分析了其构成开关电源的整体电路结构和工作原理。最后根据电路稳定准则,给出了该变换器反馈环路的详细设计方法,较好地达到了预期目标。
The control of output voltage is a key problem that must be solved in designing a high performance switching power supply.A class E2 isolated soft switch DC/DC converter is designed by means of MC33262 operating as a critical current conduction mode controller.Then the basic circuit structure and operating principle which make the switching power supply are analyzed.At last the detailed design method for the feedback circuit is presented according to the principles of circuit stabilization,which comparatively achieved the expected target as well.
