Abstract

VIENNA rectifier has emerged as a promising topology for ac-dc power converter, but it has the problem of the dc-link output voltage surge under no-load condition. In this paper, a high reliability hardware auxiliary circuit and an easy-implement software regulation algorithm are proposed to achieve voltage stability. Firstly, voltage oriented current cross-decoupling control strategy is introduced and the reason of the voltage surge has been analyzed using equivalent circuit model. Secondly, the equivalent circuit model of different working state for auxiliary circuit in association with VIENNA rectifier are described, along with introducing the selection of device parameters in the auxiliary circuit. Meanwhile, the mechanism of two working mode in the software regulation algorithm are analyzed to make the VIENNA work in boost and buck mode to achieve dc-voltage stability. Finally, the feasibility and effectiveness of the proposed methods have been verified using experimental results. The proposed methods not only suppress the dc-voltage surge, but also exhibit a good performance in terms of supply-side power factor and dc-voltage in a VIENNA rectifier, meanwhile maintaining the system adaptability under circumstance of the load step
