Abstract

This paper presents a novel AC/DC power converter topology for the future energy conversion network. The proposed Series-connected Universal Link (SUL) converter transfers the power via the high frequency transformers and single phase full bridge converters. The shape of input AC source current is sinusoidal without PWM switching of the input side converter. Thanks to the reduced reactive components and high frequency transformer, the proposed converter can increase the power density and the efficiency significantly. It is expected that the SUL converter can be easily adapted to various renewable energy sources and energy storage system. Experimental results with prototype show the effectiveness of the proposed power converter topology.
