摘要: This paper presents an optimal negative current control for four-phase interleaved bi-directional converters to achieve soft-switching features. Four-phase buck/boost with operation and in discontinuous conduction mode (DCM) are designed implemented. The is determined controlled reduce reactive power loss, while achieves ZVS ZCS turn-on the active switches converters. Variable frequency PWM also introduced fit load requirements insure DCM operation. Simulation experimental results obtained from a prototype have verified its performance feasibility.
