Abstract :
A negative KY buck converter is presented herein along with its soft switching operation. This converter can transfer the positive output to the negative output. Above all, zero voltage switching (ZVS) and zero current switching (ZCS) are used to achieve soft switching operation. Besides, the input current is limited to some extent. In this paper, the behavior of the proposed circuit is firstly described in details, and secondly some simulated and experimental results are provide to demonstrate the effectiveness of the proposed topology.
