摘要
针对双向直流变换器电压开关损耗较大,变比范围较小,传输功率密度较低等问题,提出一种新型的双向DC/DC变换器,该变换器是由Back/Boost变换器与双半桥隔离变换器组合而成的一种新型拓扑结构.建立该电路的数学模型,设计串级控制器,通过MATLAB仿真验证可行性.结果表明,这种新型变换器有较好的鲁棒性和动态响应能力,可以实现高增益、大变比、高功率密度传输.
A novel bi-directional DC/DC converter is proposed to solve the problems of high voltage switching loss,small variable ratio range,and low transmission power density of bi-directional DC/DC converter. This converter is composed of Back/Boost converter and isolated double half bridge converter.The mathematical model of the circuit is established,the cascade controller is designed,and its feasibility is verified by MATLAB simulation.The results show that the novel converter has better robustness and dynamic response ability,and it can achieve high gain,large variable ratio and high power density transmission.
