摘要: Phase shifted DC-DC converters are a well established topology for producing an isolated DC output supply. However, the conventional with LC filter has some practical difficulties when issues such as diode reverse recovery effects, voltage ratings wide ranging input voltages, and common mode EMI caused by switched transformer considered. In many applications, these can be mitigated moving inductor to AC side before bridge rectifier. this leads alternative constraints of increased series drop higher capacitor current ripple. This paper presents design equations process determine which arrangements better suits particular converter application.
