摘要:
为了进一步提高隔离型三端口变换器的变换效率和功率密度,减小功率变换器的体积,本文对隔离型三端口变换器实现软开通的条件及范围进行了研究。推导并得出了在移相调制方式下获得各端口全桥变换器开关管实现软开通的解析表达式,并通过仿真和实验室搭建的隔离型三端口变换器硬件试验电路进行了验证。仿真和实验结果与理论分析吻合,有助于实际系统研制时的辅助设计和参数优化。
Abstract:
In order to improve the conversion efficiency and power density of the isolated three-port converter and reduce the volume of the power converter, the conditions and scope of the soft turn-on of the isolated three-port converter are analyzed in this paper. The analytical expression for soft switching of full-bridge converter switch in each port is derived and obtained under phase-shift modulation mode, and the correctness of theoretical analysis and simulation results are validated based on the hardware test circuit of isolated three-port converter built in the laboratory. The simulation and experimental results are consistent with the theoretical analysis, which is helpful for the auxiliary design and parameter optimization when the actual system is developed.
