摘要
首先通过介绍硬开关电路的缺陷,引出谐振技术,分析了二次串联谐振电路,给出了基本谐振开关电路。最后通过基本谐振开关组合出一种降压软开关PWM变换器(软开关斩波器),试验结果令人满意。
The faults of hard switching circuit are presented, the resonant technique by using a square series resonant circuit is analyzed and some basic circuits of resonant switching are given. At last, a sort of Buck soft switching PWM converter (soft switching chopper) is assembled by using some of basic circuits and the test result is satisfactory.
