| Abstract |
A modified carrier-based modulation method for three-phase matrix converters is proposed. This method enhances the MC performance comparing to the “conventional†carrier-based modulation methods in regard to the switching losses and the output voltage harmonic distortion. The output current waveform is also improved in the case of the proposed modulation method with 8 commutations per switching period (TSW), but it is deteriorated in the case of 12 commutations per TSW. Due to the fact that the proposed method is applicable when that the desired voltage transfer ratio is less than 50\%, the control algorithm also adapts a carrier-based modulation method for the cases of voltage transfer ratio larger than 50\%, which is also used for comparison and evaluation of the proposed method. |
