Simulation and Implementation of Two-Quadrant Operation of Mains Operated DC Drive System

In this paper, the authors concerned with the 2-quadrant operation of a DC shunt machine operated from AC mains, focusing on the control circuits for regeneration of power. It covers modelling, simulation and hardware implementation of the motoring and generating modes on a 3.7kW 220V 1500 RPM DC shunt machine coupled to a cage induction motor. An IGBT based full bridge power electronics module works as a converter or inverter for realizing the 2 quadrants, where the voltage polarity remains the same, but the current direction gets reversed. Simulation and experimental results covering the 2 modes of operation are presented.
