IGBT Based Current Controlled

Abstract

IGBT based current controlled inverter is used for High Power applications. It is based on Voltage source inverter (VSI) and the output is in terms of current. According to reference command output current will be changed. This project presents a study of 24 Pulse Rectifier, Buck Converter, H-bridge Inverter etc. Particular Power topology is the H-bridge inverter.

Due to advances of power electronics and inverter topology, current controlled inverter is usually preferred for quick response and accurate control. Current controller forces the load current to follow the current command in some apparatus.

This major project presents a simulation of 24-Pulse Rectifier also presents the simulation of Proposed Power topology H-bridge inverter. By using multi pulse we improve the line current distortion. Thus we improved the T.H.D. This major project also presents the designing of heat sink & Power loss calculation & Driver card testing for H- bridge Inverter etc. The experimental results are obtained and presented in this thesis.
