3 半桥变换器(Half-Bridge Converter)应用举例 已知:输入电压值为 Vi 给定:变压器匝比为 n 调制:占空比为 D(T/2) 得出:输出电压值为 Vo 应用举例: 应用于输入电压为100V,隔离输出电压需求为5V,隔离变压器匝比为5。求占空比需控制在多少才能使得输出电压稳定在5V? 4 半桥变换器(Half-Bridge Converter)应用环境...
能量在谐振电路里循环,然后一部分/全部传送到输出。 在谐振变换器中,两种谐振变换器分别为串联谐振变换器series resonant converter (SRC),并联谐振变换器parallel resonant converter(PRC)。这两种变换器都通过改变开关频率调节输出,调节开关频率,使得谐振电路阻抗变化。因为串联谐振相当于输入和负载的电压分压,SRC的DC增...
