摘　　要：概括了加速器H桥非隔离式电源的运行原理与特点,在简化运行方式基础上建立了理想状态下电源连续工作模式的数学模型,并给出了仿真分析结果,介绍了基于TMS320F2808MCU实现的数字化电源控制器结构。A brief summary of H bridge non-isolated DC-DC converter and operation principles is presented in this paper. A small signal model of the ideal converter in continuous current mode is proposed and simulation results of the converter are given. The hardware structure of digital power supply controller based on TMS320F2808 MCU is introduced.
