초록
This paper presents interleaved bi-directional LDC(Low DC-DC converter) with soft-switching for 48V system of Mild-HEV(Hybrid Electric Vehicles). The proposed LDC is composed of interleaved bi-directional converter and small resonant inductor and capacitors. Comparing the conventional converter, the proposed LDC improves the problem of switching loss by employing soft-switching. In this paper, mode analysis is described in detail for operating the soft-switching. The proposed LDC is verified by PSIM simulation.
