Simulation of SPWM in Three-Phase Inverter Based on LabVIEW and Multisim

Abstract

This paper presents simulation of a three-phase single-level inverter. The inverter is designed to be fed into the power grid. State-space model and sinusoidal PWM technique are described in this paper. The simulation is based on Multisim and LabVIEW co-simulation. This method of SPWM simulation has some software and harmonic which must be taken into account while using it in the real power grid. Efforts are underway to improve the three-phase single-level inverter.
