Abstract
Recently, nine-switch inverters and nine-switch z-source inverters have been proposed as dual output inverters. In this paper, a new space vector modulation (SVM) for nine-switch and nine switch z-source inverter is proposed. The proposed method increases the sum of modulation indices about 15% in contrast with the conventional scheme in which the sum of modulation indices is equal or less than one. The extra available voltage for a given input dc-voltage, translates to a higher torque. Also, in order to further reduce the cost of power devices and also thermal heat effect reduce number of semiconductor switching, specific SVM switching pattern is presented. This feature will be advantages for high power inverter applications. The performance of the proposed SVM for both nine-switch inverter and nine-switch z-source inverter is verified by simulation and experimental results.
