“…Here, E is a dc supply voltage. The recommended PWM modulation is calculated by adding an offset, E/4, to the reference in ( 1) and the reference in (2). Therefore, The reference voltages range from -E/4 and E/4 for Inv1 and Inv2, respectively, from the above equations.…”

“…In certain applications, there is a practical need to control two or more loads simultaneously [1] independently. However, the conventional approach of using individual converters for each load introduces complexities in designing, operating, and maintaining individual converters and their control circuits [2][3]. This paper addresses the challenges associated with controlling two independent loads with a single converter topology while leveraging the power of machine learning techniques.…”

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.
