A Simplified Method of Improving the Power Quality in Power Electronic Circuits using a Single Pair of IGBTs

Abstract

This paper presents a method to reduce harmonic components in voltage-sourced circuits utilizing IGBT switches and diodes using the PWM technique and also presents a technique to improve the power quality, using a single pair of IGBTs (level-1 or stage-1). This model was developed in Simulink using the designed circuitry, which can be used for improving the power quality. The simulation results are obtained by performing the simulations in the MATLAB-Simulink environment.The simulation results demonstrate the efficacy of the method developed for harmonic suppression in power electronics-based systems, which can greatly improve the power quality.The work can also be extended to a 2-level and a 3-level inverter for an improvised versions for future works.
