Abstract

This research presents a generic pulse width modulation (PWM) approach for nine switch inverters and five-leg inverters. The circuit design of both inverters and a modulation mechanism for separate drives have been described. The available DC bus voltage supplied the two induction motors using a PWM technique for a 5-leg inverter. Nine-switch inverters and nine-switch z-source inverters have lately been presented as dual-output inverter. A nine-switch z-source inverter and a unique pulse width modulation (PWM) were created. Also, a five-leg inverter is modelled using Extended Two Arm Modulation (ETAM) scheme. The suggested modulation techniques were applied to control two machine drive systems with a single inverter architecture with a reduced switch count for pumping the water to house hold appliances. The comparative analysis of the two dual-output inverters is integral to this work.
