Abstract
A combiner circuit and voltage protection circuit is disclosed. A plurality of photovoltaic sources is provided. A set of fuses, each having one side coupled to one of the plurality of photovoltaic sources is provided. A set of contacts, each having one side coupled to the other side of one of the fuses is provided. The other side of the contacts are coupled together to combine the output of the photovoltaic sources to an output interface, the output interface being coupled to the load. A set of diodes are each coupled to each of the set of fuses and form a current path around the set of contacts. A transistor is coupled to each of the diodes and the load interface. The transistor has an on state completing the flow of current through the diodes around the set of contacts to the load interface.
