Abstract :
Employing the transformer leakage inductance and two cross-coupled capacitors, a built-in input filter forward converter (BIFFC) configuration is proposed to shape the input current waveform to a nonpulsating fashion. Consequently the ripple and harmonic component of the input current can be significantly reduced without adding a large input filter. In this paper, the circuit operation is analyzed by using the PSPICE software and an experimental circuit on a 300 kHz, 50 W converter was breadboarded for performance evaluation and comparison
