MOSFETs Zero-Voltage Switching Full-Bridge Converter ...

rating of the converter. The power rating is quadruple that used for a single-ended topology like power factor correction (PFC) or flyback. The reason is that, for a given power level, PFC stages are designed for input voltages from 100 VAC to 264 VAC, whereas the ZVSFB downstream operates from a near constant input of 400 V Note -----
