Design and analysis of a three phase differential boost inverter

Abstract

In this thesis a three phase differential boost inverter is designed . ORCAD Capture 9.1 simulations are used to perform the analysis of the inverter. The output voltage of traditional single or three phase inverter is sinusoidal at any particular frequency. But the output voltage of three phase inverter is non-sinusoidal at variable frequency. Different control technique/strategy such as linear control technique, sliding mode control technique etc has been developed where output voltage is controlled by both voltage and current feedback. To make output voltage of the designed inverter sinusoidal at different variable frequency a control circuit has been designed where only voltage feedback technique is used. The three phase differential boost inverter is designed where a reduced number of feedback from the power circuit to the control circuit is used.
