Abstract: With the increasing demand for power performance and fuel consumption of hybrid vehicle, bidirectional direct current to direct current (DC/DC) converters become one of the possible directions to meet user requirements. Based on the application of the bidirectional DC/DC converter in the hybrid vehicle, the paper analyzes the Honda power control unit (PCU) system, the different topological structures and the benefit of using the dual-way staggered topology. Analyze the problems that the bidirectional DC/DC converter may encounter in the hybrid system. And provides suggestions for the selection of bidirectional DC/DC converter for hybrid vehicle.
