Analysis of Three Phase SPWM Inverter

Saha, Shiladitya and Agarwal, Gaurav and Kumar, Kundan (2012) Analysis of Three Phase SPWM Inverter. BTech thesis.



This project deals with study of a Sinusoidal Pulse Width Modulated Inverter and all the parameters used to reduce the harmonics and give the good efficiency of the inverter. The project will be commenced by a basic understanding of the circuitry of the SPWM Inverter, the components used in its design and the reason for choosing such components in this circuitry. Generally, only single phase SPWM inverters are used industrially, and certain instabilities have been found in their operation. With improper selection of system parameters, the inverter suffers different type of instabilities and many types of harmonics. Our attempt will be to observe the same for three phase SPWM inverter and analyze its parameters used to get a pure sinusoidal output waveform and fewer harmonic in its output current and voltage waveform. It will be attempted to simulate a model circuit on any simulating software e.g. MATLAB and analyze the output waveforms for various values of the elements used in the circuit and hence observe the waveform distortion.
