Phase-shifted full-bridge PWM converters work in discontinuous current mode (DCM), when the current of out-put filterinductor is discontinuous in one switching period.
当输出滤波电感的电流在一个周期内不连续时，移相全桥PWM变换器就工作在电流断续模式（DCM）。

The harmonic characteristics of a rectifier with a DC filterinductor or capacitor are analyzed and then relevantlythey are classified into current type and voltage type harmonic source.
分析了直流侧电感和电容滤波的整流器的谐波特性，进而把它们分为电流和电压型谐波源。

By analyzing the current ripple of the filterinductor on the condition that the phase shift is different, the reduced value of the current ripple with the interleaving modulation strategy can be got.
