Abstract

This paper deals with a comparative evaluation of AC-DC power supplies with 220 V, three-phase AC input and 48 V DC output in 10 kVA power range. These are widely used AC-DC converters in many applications, particularly telecommunication systems. These converters can be categorized into three groups, first topologies based on single-phase switched mode rectifier and PWM semi-boost rectifier, second, topologies based on PWM current source rectifier and third, topologies based on PWM voltage source rectifier. Comparative evaluation includes number of active and passive components, number of control loops and complexity of control system, number of sensors, requirement of output stage isolation and performance of all the converters at input/output ports. Standard software for simulation for power electronics circuits provides steady state and transient performance of these converters. The size of all the active and passive components is set to meet the standard criteria for performance. The experimental verification of simulated results is carried out
