To solve this problem, a bridgeless SEPIC converter with ripple-free input current is proposed. In the proposed converter, the input bridge diode is removed and the conduction loss is reduced. In addition, the input current ripple is significantly reduced by utilizing an additional winding of the...

AN3180 Application note A 200 W ripple-free input current PFC pre-regulator with the L6563S Introduction A major limitation of transition-mode-operated PFC pre-regulators is their considerable input ripple current, which requires a large...
By operating the switches located in the IQBC stage with a duty ratio of 0.5 and 180° phase﹕hift, the source current ripples are nullified. Besides drawing a smooth and ripple‐free current from the input, the converter's voltage gain is adjusted by varying the duty ratio of the switch...
This paper presents three nonisolated high voltage gain dc-dc converters with ripple-free input current. The proposed converters combine coupled inductors and voltage-doubler structure (VDS) to achieve high step-up of input voltage. An active clamp circuit is used to suppress voltage spike of the...
