fs=f0,变换器的导通损耗主要由Lm决定,而不是Lr、Cr,原边管可以在全负载范围内实现ZVS开通,开关损耗主要来自关断损耗,它也由Lm决定,因为在iLr=iLm,也是iLm达到峰值时关断,因此设计一个高效率的LLC变换器,Lm需要取合适的值。 因为Q最大的曲线增益的峰值 怎样获得增益峰值曲线? Ln=5,Q=0.5作为初始设计值 B.保...
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...
The design method for CLLLC power stage is similar to the LLC converter. The resonant elements in secondary are all referred to primary and the equivalent circuit yields the transfer function. To simplify design step, reflected Lrs is assumed same as Lrp and a ratio of reflected Crs to Crp ...
