Abstract
Space Vector Modulation (SVM) and Sinusoidal Pulse Width Modulation (SPWM) are the most prominent methods used for providing gating signals on switches of a 3-phase and 1-phase Inverters. This paper presents a comparison of SVM and SPWM techniques used on a 3-phase Inverter based on the Total Harmonic Distortion (THD) of Inverter Output Voltage and Current waveforms. It has focused on the two above mentioned PWM methods which are being used to develop current controlled based model applied on three phase loads. Simulation study of 3 phase Inverter has been carried out using SPWM and SVM techniques and THD of output voltage and current waveforms of the Inverter has been compared. The results shows an improvement in output power quality of the 3-phase inverter with current controlled SVM than the current controlled SPWM.
