Abstract

This paper focuses on the implementation of two pulse width modulation (PWM) techniques on a reduced-component multilevel inverter which reduced the number of power switches along with the voltage sources used. The reduced components multilevel inverter has two circuits; level circuit and polarity circuit. The level circuit is used for producing voltage levels, whereas polarity is a conventional H-bridge used for reversing output voltage levels. The reduction in harmonics is primarily dedicated by the switching technique used to control the power switches. In this paper, two PWM techniques were applied to the presented inverter to investigate the change in the switching signal period on ripple contents and total harmonic distortion (THD) with a closed-loop voltage control system. In the closed-loop system, a conventional PI controller is used to regulate the load voltage to achieve an output voltage near to sinusoidal. MATLAB/SIMULINK has been used to analyze the overall performance of the multilevel inverter based on seven-level operation under both PWM techniques. The simulation results show that the first PWM technique, which has a low switching time for the power switches, has an influence on the THD and the ripple content by about a 6 percent reduction compared with the second technique.
