摘要
采用谐振电路和PWM开关结合 ,组成电压谐振开关 ,实现DC—DC功率变换。介绍了专用控制器MC340 6 6的性能及使用 ,给出了控制电路和功率变换电路。用这种方式设计的 2 0 0W开关电源 ,效率高 ,控制电路简单 。
In order to make DC DC power converted,voltage resonant switch is combined by resonant circuit and switching PWM.This paper also introduces how to use controller MC34066 and its circuit. After practical application,the 200 W switching power supply,designed in this way,has high efficiency,better stability and simplicity of its control circuit.
