Abstract

This paper presents a 6.5kW IGBT based DSP controlled constant voltage battery charger designed and implemented for Railway Coaches. The proposed battery charger comprises of a three phase uncontrolled bridge rectifier at the front end and an IGBT based full bridge DC-DC converter at the output end. The rectifier circuit converts the three phase 415V AC supply to DC. The rectified DC output is given as input to the full bridge DC-DC converter. The converter then generates a regulated and isolated DC voltage which is used to charge the battery. A complete analysis of full bridge DC-DC converter, design considerations and validation of simulation results are discussed in this paper.
