摘要
随着汽车自动化和电力电子技术的发展,车用电气设备越来越多样,传统的14 V供电系统已经不能满足日益增长的汽车电子设备的需要。为了兼顾传统的14 V汽车供电系统,采用一种过渡方案,即14 V/42 V双电压供电系统。对基于电压型准Z源双向DC-DC变换器的双电压供电系统进行研究。其中,双向DC-DC变换器是核心技术环节,通过PWM控制双向功率开关实现功率流的双向传输,并对该双电压供电系统的结构和工作原理做了详细的描述和简要分析。仿真结果表明了该系统的合理性和优越性。
With the development of the automobile automation and power electronic technology,the automotive electricalequipments become diverse,and the traditional14V power supply system can′t meet the needs of the increasing automotiveelectronic equipments.In order to take into account the traditional14V vehicle power supply system,a transitional scheme(14V/42V dual-voltage power supply system)is adopted in this paper.The dual-voltage power supply system based on voltage-type quasi-Z-source bidirectional DC-DC converter is studied.The bidirectional DC-DC converter as the core technology link ofthe system controls the bidirectional power switch by means of PWM to realize the bidirectional transmission of the powerflow.The structure and working principle of the dual-voltage power supply system are described in detail,and analyzed briefly.The simulation results show that the system is rational and superior.
