| 摘 要： | 提出一套基于DSP控制的工务宿营车接触网供电电源系统,给出主控芯片DSP的主要外围硬件电路设计及其工作原理说明,同时分析了系统的总体控制框图及主控制板控制算法。系统选用TMS320F2812作为中央处理器,运用增量式PI控制算法调节开关器件的移相角,很好地实现了使整流侧电压稳定的功能,并且用户端交流输出侧的电压波形正弦度较好,波形的总体谐波畸变率也小。两块DSP并行处理,大大增强了系统的可扩展性与稳定性。

| Abstract: | A design for power grid-connected power system of dormitory car based on DSP is put forward.The periph-eral hardware circuits design and the interpretation of its working principle are given,and general control chart as well as software algorithms of main control board is briefly analyzed.All expected functions,such as stabilizing the voltage of rectifier sides,is well realized while the system choose TMS320F2812 as its CPU and incremental PI algorithm as its strategy for phase shift.Furthermore,harmonic distortion rate of the waveform of AC sides is shown with excellent sinusoidal performance.Parallel processing of two DSP make good scalability as well as its stability. |
