一种交错并联零电流软开关双向DC/DC变换器设计*
Design of a interleaved parallel ZCT soft-switchingbidirectional DC/DC converter
A zero-current soft-switching interleaved parallel bidirectional DC/DC converter is designed for the problem of large loss of switching tube when the traditional interleaved parallel bidirectional DC/DC converter is operated at high frequency and high power. Through the introduction of the resonant before and after the switching process to achieve zero-current turn-on and zero- current turn-off, reduce switching losses. The working mechanism of the circuit in Boost /Buck mode is analyzed by sub - time mode, and an improved zero - current soft - switching bidirectional DC/DC converter suitable for a specific duty cycle is proposed. Finally, the simulation results show that the energy conversion efficiency of the designed zero-current soft-switching converter is improved.
