초록
Recently, Building Integrated Photovoltaic (BIPV) generation systems have been studied in renewable energy engineering field because the systems require small space installation and a reduced building material cost in spite of the performance degradation from partial shading. In case of a MIC with series connected output, it is easy to obtain a high DC-Link voltage for grid-connected applications. However, DC-Link voltage ripple also increases as the number of modules increases. In this paper, as a manner of ripple reduction, interleaved control method is applied to the PV MIC modules. For the implementation of the phase synchronization, Zigbee (Xbee-pro) wireless communications transceiver and DSP's Series Communications Interface are utilized. A 80W hardware prototype two boost-type of MIC is built to verify the DC-Link voltage ripple reduction. © 2011 IEEE.
