Abstract

Communication relay stations often suffer from common-mode noise generated by high speed switching in a boost chopper equipped for power supply. This problem can be addressed by applying soft-switching techniques to the boost chopper, although this can lead to significant increase in the circuit volume. To address this difficulty, this paper proposes a novel passive regenerative turn-off snubber applicable to the two-phase interleaved boost chopper. The proposed snubber can add small circuit volume because it is implementable only by two diodes and a capacitor. Experiments are carried out to verify the operating principles of the proposed snubber. The results successfully verified suppression of the rising speed of the drain voltage at the turn-off in both of the phases without apparent deterioration of the efficiency.
