Performance Analysis Of Two-Level Inverter By Space Vector Pulse Width Modulation Techinque

Abstract

The aim of designing a conventional inverter is to convert dc to ac output with controlled voltage magnitude, variable frequency and with negligible harmonic content. Sinusoidal PWM technique though is a solution has disadvantages like poor D.C bus utilization and difficult to implement digitally. When compared with other modulating techniques, Space Vector Pulse Width Modulation relatively provides less harmonic content, effective utilization of dc bus, and complete digital implementation by a single chip microprocessor. Due to the advantages SVM has increasing applications in power converters and motor control.                                                                   

This paper aims to analyze the performances of SVPWM controlled 2-level inverter by evaluating T.H.D, D.F and L.O.H using MATLAB.
