Abstract
Pulse width modulation strategies have been developed for indirect matrix converters (IMCs) in order to improve their performance. In indirect matrix converters, the LC input filter is used to remove input current harmonics and electromagnetic interference problems. Unfortunately, due to the existence of the input filter, the input power factor is diminished, especially during operation at low voltage outputs. In this paper, a new space vector modulation (SVM) is proposed to compensate for the input power factor of the indirect matrix converter. Both computer simulation and experimental studies through hardware implementation were performed to verify the effectiveness of the proposed modulation strategy.

Matrix converters (MCs) provide a number of advantages, including sinusoidal input and output currents, regeneration capability, and compact size with good power-to-weight ratio
We propose a new space vector modulation (SVM) method for the indirect matrix converters (IMCs), which can compensate for the input power factor without IMC performance degradation
In order to validate the effectiveness of the proposed SVM method, a laboratory prototype was set up 12 shows the experimental setupmethod, for the aIMC
