Abstract :
The topology and control method of indirect matrix converter (IMC) is discussed in the paper. The space vector pulse width modulation (SVPWM) is employed on both of the rectifier stag and the inerter stage. The adjustment method of input power factor is presented based on the input current SVPWM of the rectifier stage. According to the polarity requirement of dc-link voltage, the regulation range of input power factor angle is determined. In addition, the influence of input LC filter on input power factor is analyzed. The calculation formula of input power factor angle at the grid side is presented. Simulation and experimental results validate the theoretical analysis.
