Abstract :
Employing the transformer leakage inductance, one cross-coupled capacitor, and four switches, an Input Current Ripple Reduction Converter (ICRRC) with Full-Bridge configuration for off-line high power applications is proposed. By adding two extra diodes, it provides input current ripple reduction, voltage-clamped and voltage-sharing functions. Consequently, continuous input current, low voltage stress and high efficiency performance can be achieved. In this paper, the circuit operation is illustrated and an experimental circuit of a 100 kHz, 15 V/20 A is described.
