Abstract :
A continuous current mode boost converter with modified flying capacitor lossless snubber is proposed in this paper. The proposed converter charges the flying capacitor using a coupled inductor without the help of the reverse recovery current. As a result, it can reduce switching loss and guarantee the wide snubber reset ranges. The operation principle, characteristics, and experimental results are presented to verify the feasibility of the proposed converter.
