| 摘 要： | 矩阵变换器无中间直流环节,易受电网扰动和负载扰动的影响,为此采用无源性原理的控制方法设计了输入整流侧的控制器,并且加入适当的阻尼改善了控制系统特性.此外,通过矩阵变换器的降阶分解,简化了控制器结构和提高了控制器的可实现性.结果表明,在输入电压干扰和载扰扰动下,仍能保证输入电流为正弦波,避免了对电网造成污染.

| Abstract: | Because there is no DC loop in the matrix converter, a matrix convert is sensitive to the disturbance in the grid voltage and the disturbance of the load. To deal with this problem, we develop a passivity-based controller in the input side, and introduce an appropriate damping to the control loop to improve the characteristics of the matrix converter. Besides, the structure of the control system is simplified by reducing the model-order, facilitating the implementation of the controller. Simulation results show that the input current maintains the sinusoidal waveform under the disturbances in input voltage and from the load, thus causing no pollution to the grids. |
