Title: Suppression & Comparison of Magnetizing Current of a Transformer with PWM Voltage Source Converter
Authors: Sridevi Tirunagari and Ramesh Reddy Kolli
Abstract: This paper discusses about inrush current phenomenon in a single phase and 3-Phase transformer initially in the absence of any inrush current suppressing device and then with Pulse Width Modulated voltage source converter and is compared with other technique having dc voltage regulation using PI controller. In both the proposed techniques main transformer is connected in series to a PWM voltage source converter through a matching transformer to the source. As the PWM converter is connected in series to the source it acts as a resistor for the source current there by producing no inrush phenomenon. Inrush current suppression principles for both methods were discussed with the help of block diagrams. Variation of magnetizing current with varying control gains is discussed in both the cases and the results were shown to confirm the validity. Both the methods were developed & simulated in MATLAB/SIMULINK environment.
Keywords: Inrush current, PWM converter, PI Controller, DC regulation.
