摘要

Recently, installation of photovoltaic power systems such as building-integrated photovoltaic in urban area has been spotlighted in renewable energy engineering field, even at the expense of the performance degradation from partial shading. The efficiency degradation of maximum power point tracking (MPPT) performance can be compensated by a kind of power-conditioning system architecture such as module-integrated converters (MIC), which can handle the optimal-operation tracking for its own photovoltaic (PV) module. In case of a MIC with series-connected outputs, it is easy to obtain a high DC-link voltage for multiple stage PV power conditioning applications. However, switching ripple of the DC-link voltage also increases as number of the modules increases.
