초록

The non-isolated interleaved buck converter (NIBC) is suitable for high-power fast chargers. To realize both high efficiency and high power density, soft switching technology can be employed. Many soft switching methods cannot be widely used in industry applications. In addition, they often fail to fully achieve high efficiency, high reliability, and low complexity. This paper proposed a zero current switching method, with low additional conduction losses, low current stress, high efficiency, and easy implementation. These advantages make the proposed NIBC suitable for industrial applications and especially suitable for SiC based converters. The operating principle of the proposed ZCS NIBC and the control method for the proposed auxiliary circuit are analyzed in detail. In addition, the parameters design method is discussed. Experiments are conducted on a 2 kW three phase NIBC to verify the proposed ZCS method. The obtained results demonstrate that the zero current turn on process is easily achieved and the efficiency of the proposed NIBC is higher than that of the hard switching NIBC during the entire load range.
