摘　　要：设计了一套基于SVPWM技术以TMS320F2812DSP为控制核心的铁锂电池充放电控制系统。该系统的硬件电路设计包括主电路、电压电流采集电路以及DSP控制电路等,并给出各电路详细的工作原理;研究了算法的数字化实现并设计了控制框图,给出了包括主程序,SVPWM波产生程序,充放电程序等程序模块的流程图;通过Matlab对所设计系统模型进行仿真。仿真结果验证了电路拓扑结构的正确性和控制方案的可行性。The design of lithium iron charge and discharge control system based on the technology of SVPWM and with TMS320F2812 DSP as control chip was introduced in the paper. Firstly, hardware circuits of the system were designed, including power circuit, voltage and current sampling circuits, and DSP control circuit. Subsequently, the principle of each circuit was presented in detail. Then, the digital realization of the algorithm was developed and the architectural control diagram was designed herein, and the flow charts of program module were given out, which included main program, SVPWM generating program, charge and discharge program, and etc. At last, the designed system model was simulated by Matlab. Through the analysis of waveform, the correctness of the circuit topology architecture and the practicability of the control plan were verified.
