Abstract

Employing the transformer leakage inductance and two cross-coupled capacitors, a built-in input filter forward converter (BIFFC) configuration is proposed. Without adding extra components, this configuration can perform core reset, turn-off snubber, voltage-clamped and input filter functions. Consequently, low voltage stress, high efficiency performance and reduced input current ripple can be achieved. In this paper, the circuit operation is analyzed by using the PSpice software. Based on the simulation results, the design guideline is provided and an experimental circuit on a 300 kHz, 50 W converter was breadboarded for performance evaluation
