A novel multioutput forward-flyback converter with secondary side post regulation

In this paper, a novel multioutput forward-flyback converter with secondary side post regulation is proposed. This converter can output the high power using forward converter, and low power in flyback converter. So it combines the advantage of high efficiency of forward and the low cost of flyback and also has tightly regulated outputs. The operation principle of the converter is discussed, and verified on an experimental prototype on 250 W.
