摘要：
Employing a voltage-clamped network and one additional switch to the forward converter with ripple reduction (FRR), a two-switch RCD-clamped FRR (RCDFRR) is proposed. In addition to inheriting the advantages of the FRR, it can surpass the maximum 50% duty cycle limitation with simple implementation. Consequently, the proposed converter is suitable for wide input-voltage range applications. In this paper, the circuit operation is analyzed and the experimental circuit of a 180 kHz, 36-75V input voltage and 5V/30A output power is described.
