Comparative Study of SPWM and SVPWM of Solar Fed Induction Motor using Push–Pull Converter

Abstract

Three-phase induction motors are the most useful machines in industry because they are slightly less costly and rugged due to the absence of commutator part. They are the driving work horse for most of the operations such as industries, agriculture, commercial complexes, etc. Nowadays people are chasing alternate energy sources due to the paucity of non-renewable energy sources. Because of which they are moving towards renewable energy sources. A new topology of induction motor drive system integrating a push–pull converter and a three-phase inverter using a single solar photovoltaic panel is proposed. To step-up the solar panel voltage, a DC-DC push–pull topology is employed. To obtain optimum motor performance and to reduce total harmonic distortion of the inverter output waveform, sinusoidal pulse width modulation (SPWM) and space vector pulse width modulation (SVPWM) technique are employed for switching of inverter power circuit and results are compared. Maximum power point tracking algorithm (Perturb & Observe) is used to extract maximum power from photovoltaic panel.
