Four-quadrant bi-directional drive system based on PWM DC-DC converter

Abstract

A novel four-quadrant bi-directional drive system for a DC motor based on PWM DC-DC converter is presented. The converter provides both a positive and negative output voltage, which is supplied to the splitted armature circuit of the DC motor. The converter offers both the motoring and regenerative braking mode of operation. SPICE simulation and the experimental verification of the proposed system prove the ability and the advantages of the new solution.
