摘要
讨论了一种采用状态变量反馈控制的三相正弦波逆变器，在较重的非线性负载下仍能保持负载输入端的波形较好。这种控制方式可以很容易地推广到其它电力电子装置的控制器中。提出了一种易于用计算机控制实现的脉宽调制（ＰＷＭ）开关控制模式，这种控制模式具有开关损耗较小的优点。
three-phase PWM sinusoidal voltage source inverter controlled by the statevariable feedback controller is discussed. Transforming state-variables which describe theinverter and the load to d-q system makes the control algorithm easy to implement. Thecontrol method discussed in the paper can also be used in other power electronic devices. Anew PWM switching pattern is present. The switching pattern can reduce the number ofswitching times so that can reduce switching loss. Computer simulation results are given.
