Abstract
A method for converting power from a photovoltaic (PV) panel having substrings of PV cells, the method includes converting power from a first substring of the PV panel to generate a first DC output having a fixed portion and a variable portion, converting power from a second substring of the PV panel to generate a second DC output having a fixed portion and a variable portion, and combining the first and second DC outputs to generate a combined DC output. A power converter may include an open-loop switching stage to receive DC power, a transformer having a primary winding coupled to the open-loop switching stage, and first and second secondary windings, a first rectifier bridge coupled to the first secondary winding, a second rectifier bridge coupled to the second secondary winding, and a regulator coupled to the second rectifier bridge.
