In this dissertation , a novel bidirectional dc / dc converter ' s topology was designed , witch used in vehicle power supply systems . the converter is composed of fundamental bidirectional switch cell , using phase - shifted full - bridge zvs pwm dc / dc converter in buck circuit and using push - pull boost converter in boost circuit
2.
Due to the deficiency of the typical zvt - pwm buck converter , the design of a new zvt - pwm buck converter is described in this paper . the experimental results and simulation results all approved the improvement measurements can improve the converter efficiency . in the end of the paper , a improved two - phases zvt - pwm buck circuit is brought forward base the same principle
