Abstract:
1. A photovoltaic power generating system comprising: a power-generating portion including plural parallel strings of power-generating photovoltaic modules, the power-generating photovoltaic modules being coupled in series in each of the parallel strings, each string of the plural strings and each of the modules having an output; a plurality of DC/DC micro-converters, each micro-converter of the plurality of DC/DC micro-converters being coupled to a regulated DC voltage buss and to the output of a corresponding photovoltaic module or to the output of a corresponding string of photovoltaic modules, wherein each micro-converter of said plurality of micro-converters includes: at least one semiconductor device having a breakdown voltage, at least one semiconductor switching device, and an active clamp device; an inverter that is coupled to the regulated DC voltage buss and to a load; and a control system that is structured and arranged to control each string of photovoltaic modules.
