Aiming at structural features of secondary side passive-clamped full-bridge soft switching pulse width modulation converter, this paper discussed the main cause and consequence of transformer in generation of bias and methods of traditional biasing suppression. Discussion was made to the feasibility to use series DC-blocking capacitor to suppress biasing, and a kind of new type peak current biasing suppression plan was raised. The new plan can reduce traditional peak current control method error. Matlab simulation result shows that the method can effectively suppress biasing.
