基于空间矢量调制的升压型矩阵式变换器的实现

The Implementation of Boosting Type Matrix Converter Based on Space Vector Modulation

矩阵式电力变换器具有无中间直流环节等诸多优点,但是其电压传输比被限制在0.866以下,严重影响了在电气传动领域的应用。为此提出了一种新型的升压型矩阵式变换器以及其相应的空间矢量调制策略,通过对其进行空间矢量调制能使电压传输比超过1。仿真实验表明通过空间矢量调制的升压型矩阵式变换器能够突破电压传输比0.866的瓶颈,为工程使用提供了理论依据。

Matrix converter is a direct power converter that can convert energy from an ac source to an ac load without the need of the bulky and limited-lifetime storage elements in the de link. But its voltage transfer ratio is limited to O. 866, which badly affects its usage in the field of electrical drive. The voltage transfer ratio can be much greater than before through the boosting type matrix converter by space vector modulation. And it provides theory basis for the practical engineering.
