Sinusoidal and Space Vector Pulse Width Modulation for Inverter

Inverters inherently have the property of controlling output frequency but the output voltage can’t be varied. Usually to vary output voltage we have to vary supply voltage which is not always possible for this reason PWM techniques gained momentum. Basic aim of PWM technique is to control output voltage and harmonic reduction. Pulse-width modulation (PWM), or pulseduration modulation (PDM), is...

Design and Performance Analysis of 7-Level Diode Clamped Multilevel Inverter Using Modified Space Vector Pulse Width Modulation Techniques

In this paper, a 7-level Diode Clamped Multilevel Inverter (DCMLI) is simulated with three different carrier PWM techniques. Here, Carrier based Sinusoidal Pulse Width Modulation (SPWM), Third Harmonic Injected Pulse Width Modulation (THIPWM) and Modified Carrier-Based Space Vector Pulse Width Modulation (SVPWM) are used as modulation strategies. These modulation strategies include Phase Dispos...

Vector controlled PMLSM using simplified Space vector pulse width modulation

This paper aims to develop vector controlled permanent magnet linear synchronous motor (PMLSM) based on simplified space vector pulse width modulation. Mathematical models of PMLSM&SVPWM presented. The present PWM technique does not involve any sector identification and considerably reduces the computation time when compared to conventional space vector PWM technique. To validate the proposed a...

Design of Three Phase Inverter Using Space Vector Pulse Width Modulation Technique (SVPWM)

A voltage source inverter is commonly used to supply a three-phase induction motor with variable frequency and variable voltage for variable speed applications. A suitable pulse width modulation (PWM) technique is employed to obtain the required output voltage in the line side of the inverter. The different methods for PWM generation can be broadly classified into Triangle comparison based PWM ...
