Abstract

A novel medium-frequency-transformer isolated matrix converter topology for wind energy conversion applications is proposed in this paper. The proposed topology consists of single-phase cascaded AC-AC converters on the utility side and three-phase matrix converters on the PMSG side, with medium frequency transformers as isolation. No DC-link capacitors or resonant L-C circuits is needed thus increases the reliability as well as the power density in the system. Utility power factor control may be realized without difficulty so that it is suitable for reactive power generation of WTG low voltage ride through. This configuration could be used as a medium-voltage utility interface of wind power generation and applications. The feasibility of the proposed topology and its modulation and control strategy has been verified by simulation and experimental results.
