Gate driver design with phase shift SPWM technique on H-bridge multilevel inverter topology

A converter that converts DC to AC electricity with more than two voltage output levels is known as a multilevel inverter. Eight power switch components (MOSFETs) are used in the 5-Level H-Bridge Multilevel Inverter (CHB-MLI) topology, which is currently being developed. CHB-MLI 5-Level is made up of two full bridge inverters connected in series for each phase. To get positive and negative cycle output from CHB-MLI, a separator is required for each full bridge inverter. The 5-level CHB-MLI uses the PWM (Pulse Width Modulation) technique as a switching technique. This PWM technique, is used as a switch in a power switch component (MOSFET) to determine the harmonics produced by a multilevel inverter. Hence, the harmonics of the 5-level CHB-MLI output voltage were analyzed against the switch model using the Sinus Pulse Width Modulation (SPWM) method, and the Phase Shift Sinus Pulse Width Modulation (PSSPWM) method. The results show that the 5-level output voltage harmonics in the PSPWM method are least than the SPWM method.
