摘要提出了矩阵变换器电压控制性能的改进方案。通常，由于换流方法、输出电压误差以及诸如输入电压失真和不平衡的输入电压干扰，电压控制性能劣化。首先，本文介绍了两种类型的换流方法。通过仿真比较了两种方法的开关损耗，并通过实验比较了两种方法的变换器效率。其次，本文对输出电压误差进行了分析，并提出了一种误差补偿方案。实验结果表明，该补偿方法可以有效地降低输出电流的总谐波失真。最后，为了减小输入电压扰动对输出电压的影响，提出了一种新的输入电压扰动补偿方法。仿真和实验证明了该方法的有效性。电机驱动特性的22千瓦原型型矩阵变换器，配备所提出的方法，也示出。
Abstract This paper proposes improvement schemes of the voltage control performance for the matrix converter. The voltage control performance is deteriorated because of the commutation method, the output voltage error, and the input voltage disturbance such as the input voltage distortion and unbalance, in general. Firstly, two types of the commutation methods are described in this paper. The switching loss is compared through simulations, and the converter efficiency is compared through experiments on the two methods. Secondly, the output voltage error is analyzed and an error compensation scheme is proposed in this paper. The experimental results show the THD of the output current can be decreased with the proposed compensation. Finally, in order to decrease the distortion of the output voltage in case of the input voltage disturbance, a novel compensation method for the input voltage disturbance is proposed. The adequacy of the method is proved by simulations and experiments. Motor drive characteristics of a 22kW proto type matrix converter, equipped with the proposed methods, are also shown.
