The Comparison of SPWM, SHEPWM, HIPWM and SVPWM Techniques on 3-Phase Inverter Circuit

The main usage reason of inverters which are used in many medium and high voltage applications such as motor driving systems, UPSs, voltage compensators and etc. converts Direct Current to Alternative Current. Inverters can be produced as single-phase and three-phase, or they can be classified as Voltage Source Inverters or Current Source Inverters according to their supply sources. In this study, 3-phase Inverter circuit which are used Sinusoidal Pulse Width Modulation Technique (SPWM), Selective Harmonic Elimination Pulse Width Modulation Technique (SHEPWM), Third Harmonic Injection Pulse Width Modulation Technique (THIPWM) and Space Vector Pulse Width Modulation Technique (SVPWM) feeding R-L load are presented by using MATLAB/Simulink program and current and voltage waveforms are given comparably
