    Analysis and Implementation of Carrier Based and Space Vector PWM Techniques on a Three-Phase Voltage Source Inverter

    By michael opare atakora, Arbin Ebrahim, Ji Hyun Lee

    Abstract: This paper presents a comprehensive analysis of carrier based and space vector pulse width modulation (PWM) techniques on a two-level three-phase voltage source inverter (VSI). The results of simulations performed in Matlab/Simulink are compared to the results obtained from the implementation of the PWM schemes on an actual VSI whose PWM signals are generated using dSpace. The analysis of the inverter line to line voltages includes, a fast fourier transform …

    Matlab/Simulink Implementation and Analysis of SVPWM, SPWM and THIPWM: A Modular Approach

    By michael opare atakora, arbin abrahim, Ji Hyun Lee

    Abstract: The SVPWM technique has become more popular today than ever before due to the availability of fast digital systems for implementing this switching scheme. This is the preferred switching scheme for three phase inverters when compared to traditional SPWM. This paper describes a modular implementation and analysis of three popular switching methods employed in voltage source inverters: Space Vector Pulse Width Modulation (SVPWM), Sinusoidal Pulse Width Modulation (SPWM) and Third …
