摘　　要：介绍了一种应用于车载数字化充电电源上的隔离型移相控制对称半桥双向DC/DC变换器的拓扑结构,分析了变换器的工作原理,并根据现代控制理论建立了该变换器的状态空间平均数学模型。在此基础上,设计了以TI公司DSP芯片TMS320F2812为处理器的控制系统,并阐述了一种简单可靠的基于DSP的移相脉冲生成方法。研制了试验样机,并进行了试验研究,试验结果证实了理论分析的正确性。A topology of isolated phase shift control symmetrical half bridge bi-directional DC/DC converter which is applied to digital charging power supply on vehicle, is introduced in this paper. The operation theory of the converter is analyzed in detail. The state space average mathematics model is obtained according to modern control theory. The paper designs the control system based on TMS320F2812 Hereby, explicates a simple and reliable method which produce phase shift pulse based on DSP. A prototype is established and some experiments have been done. The experiment results have verified the validity of the theoretical analysis.
