Continuous Load Current Mode Analysis of Phase-Controlled AC to DC Converters.

Abstract

In this paper, an insightful analysis of controlled AC to DC converters operating under continuous load current mode is presented. The midpoint converter, as the basic building block of other AC to DC converter application circuits, is first analyzed in positive and negative conversion modes. The full bridge converter, fully controlled, is shown to comprise a positive and negative midpoint converter sharing a common AC input and differentially supplying a common output load. The analysis results can be used to predict the output performance of any standard phase controlled converter application circuit with any given number of AC input phases and/or output pulses under continuous load current. The software for simulation is Ansoft SIMPLORER®.
