抑制矩阵变换器共模电压的间接调制改进方法
Improved Indirect Modulation Methods for Suppressing the Common-mode Voltage of Matrix Converter
摘要
Abstract
To solve the problem that the common-mode voltage of a matrix converter has a negative effect on the motor system,two improved indirect space vector modulation methods are proposed in this paper. The first method is to syn?thesize the reference current on the rectifier stage by using three adjacent active vectors in the high modulation index range of the matrix converter. The second method is to synthesize the reference current by using active vectors in two in?tervals and a suitable zero vector in the low modulation index range. In addition,the inverter stage of the two modula?tion methods does not use any zero vector. Compared with the traditional modulation method,the modulation methods proposed in this paper not only reduce the peak value of the common-mode voltage to 3 times of the input voltage am?plitude,but also reduce the switching loss on the inverter stage. The effectiveness of these two modulation methods was verified through simulation and experimental results.关键词
