Research, design and manufacturing of mine battery chargers using switch mode power technology

Abstract

    Currently, battery chargers for mine electric trains are using controlled rectifier circuits that have many disadvantages.In recent years, Switch Mode Power Supply technology has appeared to overcome most of the disadvantages of currently used rectifier chargers. The article presents some results of research, design and manufacturing of battery chargers for battery charging stations using SMPS technology. The experimental results show that the charger works stably in the pulse width adjustment range from 2% to 100%.
