摘要
对矩阵变换器的工作原理和调制策略进行了分析,对不对称输入电压下矩阵变换器的输出特性及其产生原因进行了说明,在此基础上提出了保持矩阵变换器输出三相对称正弦电压的条件,介绍了满足这一条件的两种简单可行的方法,仿真结果说明了该方法的有效性.
The principle and modulation strategy of matrix converter are analyzed. The output performance under unbalanced input voltage is introduced and the reason that leads to the performance is also addressed. Based on it, the requirement is put forward that guarantee the balanced sinusoidal output voltage under unbalance grid supply. Two implementations to satisfy the requirement are proposed. In the end, simulations are developed to verify the method.
