摘要
为了克服传统整流器功率因数低和谐波大的缺陷,设计出功率因数可调以及能量双向流动的三相电压型整流器。从其结构与数学模型两方面入手,结合矢量控制和比例积分调节原理,提出了SVPWM的实现方法。在以TMS320LF2407型DSP为平台的目标系统上,进行程序编写和调试,获得了完整的网侧电流电压波形。实验结果表明,在该控制策略下,输入电压电流波形良好且同相位,系统性能优良。
For designing a three-phase voltage rectifier with power factor tunableness and energy bidirectional flow,overcoming traditional rectifier's fault of low power factor and great harmonic,the structure and mathematical model of three-phase vohage rectifier are discussed.Based on the current tracking control with the help of PI regulate and principle of vevtor control,space vector control is realized.The programm and debugging are completed on the DSP TMS320LF2407, find the input voltage and current waveform is perfect.Experimental results proved the excellent of this control tactics.
