浅析基于矩阵变频的异步电机四象限运行控制

矩阵式变频电路是一种较为新颖的直接变频电路,在实际应用过程中,以正弦波作为输出电压,其频率不会受到电网频率的过多影响,具有十分显著的应用优势。基于此,本文就采用矩阵变频的异步电机四象限运行控制展开分析,首先,介绍了异步电机四象限运行原理,进一步对基于矩阵变频异步电机四象限运行控制系统设计进行了分析,主要内容包括矩阵变频原理与矩阵变频空间矢量调制。

The matrix converter circuit is a relatively novel direct frequency conversion circuit, in the process of practical application,with sine wave as the output voltage, the frequency are not subject to the power grid frequency of too much, has the extremely obviousapplication advantages. Based on this, this paper adopts the matrix converter is four quadrant operation of induction motor control analysis,first of all, the four quadrant operation principle of the asynchronous motor are introduced, and further to four quadrant operation ofasynchronous motor based on matrix converter control system design are analyzed, the main content includes the principle of matrixconverter and matrix frequency space vector modulation.
