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.

This paper describes a useful modulated, asymmetric full-bridge converter for sustainable solar PV applications. The suggested converter achieves zero-voltage switching (ZVS) on the main side’s power switches and reduces circulating current loss by utilizing a full-bridge architecture and an asymmetric control method. The blocking capacitor and the leakage inductance of the transformer operate in resonance to further provide the Zero Current Switching (ZCS) off for the output diode without the need for any further circuitry. Output diode reverse recovery is no longer a concern as a result. Additional connections to the input voltage include the power switch voltage stresses. Because of these features, the suggested converter has the infrastructure to reduce power losses. The buildings of renewable energy sources can benefit especially from it.
