Abstract

A photovoltaic (PV) system uses an AC module integrated converter (MIC) to operate PV cells at a maximum power point (MPP) and for high efficiency. The MPP of a PV cell varies depending on partial shading conditions, and loss occurs differently according to the configuration method of the PV-MIC. Therefore, this study compares the losses of passive components and power semiconductors according to the partial shading conditions of the PV module. Theoretical loss analysis is performed using parameters for the datasheet and PSIM simulation results. Analysis results verify that the one-stage PV-MIC demonstrates high efficiency.
