Abstract :
This paper describes the practical aspects of building modular power supply for telecom application. The latest requirements of the telecom industry calls for high efficient power supplies capable of handling large input voltage variation. The power supplies are required to produce high input power factor and low input current harmonic distortion. In addition to the above the power supplies should be of lightweight, smaller in dimension and modular in construction. Although there are lot of papers on power factor correction (PFC) circuits, soft switching converters, active current sharing circuits, RFI/EMI etc., no or very few papers provide a complete solution for an industrial power supply. In this paper an attempt is made to provide a complete, economical and a viable solution for building a telecom power supply which meets or exceeds the requirements of the telecom industry
