Abstract

This paper focuses on design and development of SPWM three-phase voltage source inverter in MATLAB/SIMULINK. Pulse Width Modulation variable speed drives are mainly applied in many industrial applications that require better performance. Recently, new developments in power electronics and semiconductor technology have lead improvements in power electronic systems. Variable voltage and frequency supply to A.C. drives is obtained from a Voltage Source Inverter which can be a 1-ɸ and 3-ɸ VSI. There are number of Pulse width modulation (PWM) schemes which are used to obtain variable voltage and frequency supply. The mainly used PWM schemes for 3-ɸ Voltage Source Inverters are Carrier-Based Sinusoidal PWM and Space Vector PWM (SVPWM). There is an increasing trend of using Sinusoidal PWM (SPWM) because it can be easily digital realized. In this paper detail analysis of SPWM three-phase voltage source inverter has been carried out at different carrier frequencies with different loads. The 3-ɸ VSI is fed from a AC-DC converter. Simulation results of output currents are obtained and their THD’s are compared using MATLAB/Simulink environment.
