AN INTRA-MODULE DC-DC CONVERTER AND A PV-MODULE COMPRISING SAME

The present invention relates to an intra-module DC-DC power converter and a Photovoltaic (PV) module comprising same. The switching frequency of said intra-module DC-DC power converters may be 500 k Hz. The PV module may have a controller and a plurality of switches for allowing each individual string of said PV module to be connected to one corresponding DC-DC converter, or for allowing two or more strings of said module to be connected in series and to apply the voltage of the combined string to a single DC-DC converter. The input voltage range of the DC-DC converters may be 10V to 30V, and the output voltage range may be 120V. The DC-DC converters may be connected in series or in parallel. Multiple such PV panels may be connected in a DC-grid.
