摘　　要：通过对电流追踪型ＰＷＭ逆变器的研究，提出了一种新型的基于电流偏差向量的控制策略，它能在稳态时抑制电流高频谐波，在动态时又保证电流快速响应，介绍了其工作原理，并给出了在电压型逆变器中实现该ＰＷＭ控制的电压矢量限定及选择原则．系统由８０９８单片机、信号处理器、ＥＸＢ８４０驱动器和ＩＧＢＴ功放电路等部件组成，试验证明了该方法的可行性及合理性。This papre proposes a novel control strategy based on current-deviation-vector.It has a quick current response in transient state and a low harmonic current content in steady state,The edicle presents the principle of this control strategy.The voltage vector limitation and selection principle for a constant voltage source PWM inverter and the experimental results of a microprocessor-based PWM us-ing this method are also given.The system is consised of 8098 microprocessor control unit,singnal pro-cessor,EXB840 driving circuit and IGBT power device,experiments proved the feasibility and reiabili-ty of this theory.
