In order to further improve the voltage transfer ratio (VTR) of indirect matrix converter (IMC), a novel space vector overmodulation strategy by modifying the modulation in rectifier stage is proposed. This strategy increases the VTR to 1.05 and achieves no magnitude error between the fundamental output voltage and the reference output voltage. Based on the conventional overmodulation region I and II, the overmodulation region III is added. The main low frequency harmonic component of input and output current is analyzed. Finally, the validity of the novel overmodulation strategy and the correctness of the input and output low frequency harmonic characteristics are verified by experiments.
