摘要
针对如何提高电压源型三相PWM整流器交流侧电流的控制速度问题,本文提出了控制和调制相结合的两种控制策略,即电流的空间矢量滞环控制策略和优化的电流空间矢量控制策略。本文分别对这两种控制策略进行了仿真,仿真结果验证了两种策略的有效性。
To improve the control speed of three- phase PWM VSI's ac-side current, two-space vector current control strategies are proposed respectively named current-space -vector hysteresis control based on projection method and optimized current-space-vector control. This paper has some guiding significance on occasions where high switching speed is demanding. Simulation verifies the validity of the two control methods by use of the Matlab/simulink paekage.
