摘要
本文提出了一种基于空间矢量脉宽调制(SVPWM)的直接电流控制策略的三相电压型PWM整流器,给出了它的拓扑结构及数学模型。为了提高系统的可靠性,优化了主电路结构设计及控制系统软硬件设计,并搭建了样机进行试验。试验结果表明三相PWM整流器带负载运行效果良好,所设计的控制系统具有很好的稳态和动态性能。
This paper presents a direct current control strategy based on space vector pulse modulation. It also presents the topology and the mathematical model of voltage source rectifier, and optimizes the structure, hardware and software of the control system. A prototype of experimental device was developed and tested with PWM rectifier. The static and dynamic performance of the proposed controlling system was verified by the operating experiments, and it shows the control system has a good stability and dynamic performance.
