摘要
介绍了采用８７５１单片机及其相关的接口电路构成的ＶＶＶＦ地铁空调电源，详细论述了系统各组成部分的工作原理、硬件实现方法及控制软件流程．经在北京地铁车辆中运行证明，该系统很好地适应了地铁断电区的要求，具有控制灵活方便和保护功能完善、抗干扰性能强、运行稳定、安全可靠等优点．
The Paper intnduces a novel VVVF(Variable Voltage Variable Frequency)inverter used for subway air conditioner,which cousins of 8751 microprocessor and its peripheral interface. The operation printiple,hardware construction and basic software block diagram are described in detail. Practical operation experiments in the subway in Beijing show that the inverter is a novel power supply with excellent performances for subway air conditioner, convenient control, perfect protection & antiinterference,stable and safe running.
