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.

三相交流/直流稳压电源:不同拓扑结构的比较评估

本文对10kva功率范围内220v、三相交流和48v直流的交直流电源进行了比较评价。这些是广泛使用的交流-直流转换器在许多应用，特别是电信系统。这些变换器可以分为三类，第一种是基于单相开关整流器和PWM半升压整流器的拓扑结构，第二种是基于PWM电流源整流器的拓扑结构，第三种是基于PWM电压源整流器的拓扑结构。比较评估包括有源和无源元件的数量、控制回路的数量和控制系统的复杂性、传感器的数量、输出级隔离的要求和输入/输出端口所有变换器的性能。用于电力电子电路仿真的标准软件提供了这些转换器的稳态和瞬态性能。所有有源和无源元件的尺寸都设置为符合标准的性能标准。对仿真结果进行了实验验证。
