Study and Implementation of 19-Level Multilevel Inverter and its Onfigurations

Abstract

We can't envision a day in the twenty-first century without electrical appliances, and the most important thing is to have an uninterrupted power supply. In the construction of a continuous running power supply system, the inverter is an essential part. This project proposes a novel pulse-width-modulated (PWM) control scheme and a nineteen-level single-phase multilevel inverter with reduced switch count. The output voltage level of the proposed multilevel inverter is increased by using eight switches driven by multi-carrier modulation techniques. The inverter can generate 19 levels of output voltage from the dc supply voltage using an asymmetrical configuration. The proposed system was tested using MATLAB simulation, and the DSPIC30F2010 controller was used to implement the hardware.
