Summary:This letter proposes a new push-pull dc/dc converter topology with complementary active clamped. First, a clamping capacitor is added between the active switches to maintain a clamping voltage and recover the energy stored in the leakage inductors. Second, the leakage inductors of transformer are effectively utilized to buffer the energy transfer, and greater leakage inductors are expected. Third, the active switches are mutually clamped via the added capacitor, and the natural soft-switching characteristics are given. Fourth, the rectifier diodes commutate naturally without reverse recovery. Finally, an experimental prototype is designed, and the correctness of the theoretical analysis is verified.
