Design of 21-level LUO Progression based Multi-Level Inverter using Cross-compiling

Abstract

This paper proposes the design of a 21-level LUO progression-based inverter. The driving switch patterns are generated using the VHDL code and cross-compiled in the MATLAB SIMULINK tool. Though there are several inverter topologies, the LUO progression-based inverter consists of less number of switches and low design complexity. The proposed method includes the utilization of carrier-free pulse width modulation signals for the switches to generate the 21-level Multi-Level Inverter. The carrier-free modulation technique is referred to as Switching Angle Method. The performance of the proposed method is evaluated for THD%, VPEAK, and VRMS. The proposed method is developed with the Integrated Circuit layout and its analysis using the Cadence tool.
