| 摘 要： | 针对大功率脉冲负载在船舶领域中的应用为背景,对其中全桥隔离DC/DC变换器展开研究。本文基于最小回流功率的双重移相控制策略,通过分析双重移相控制下的软开关条件及其功率传输特性,建立了其动态小信号模型。最后通过Matlab/Simulink仿真实验对控制策略进行验证,实验结果表明了采用基于最小回流功率控制对提高变换器效率的有效性。

| Abstract: | For the background of the usage of the high-power pulse load in the ship, this paper focused on the full-bridge isolated DC/DC converter. Through analyzing the soft-switching conditions and the power transmission characteristics with the dual-phase-shifting control, which based on the strategy of minimum backflow power, the dynamic small signal model is presented. At last, it verified the validity to promote the efficiency of the converter, which used the control of minimum backflow power by simulation experiment with Matlab/Simulink. |
