提出了一种具有统一功率因数的容错ac-ac变换器，能够从电网为三相感应电机供电。其中一个变流器支腿发生故障，其余五个支腿中的两个与电网连接，两个支腿与机器连接，一个公共支腿由电网和机器共享。以前开发的控制策略需要大量的计算时间，难以实际实现。本文针对该功率变换器提出了一种新的控制策略。它支持更简单的控制实现。给出了实验结果。
A fault-tolerant ac-ac converter capable of supplying a three-phase induction machine from the grid with an unitary power factor has been proposed. With one faulted converter leg, two of the remaining five legs are connected to the grid, two legs are connected to the machine, and a common leg is shared by the grid and the machine. The previously developed control strategy required a too great computation time for practical implementation. In this paper, a new control strategy is suggested for this power converter. It enables an easier control implementation. Experimental results are provided.
