Abstract
A method and apparatus for determining an operating voltage lower bound for preventing photovoltaic (PV) cell reverse breakdown during power conversion. The method comprises determining a PV cell operating temperature; computing, at a controller, an operating voltage corresponding to a maximum power point (MPP) based on the PV cell operating temperature; and determining, at the controller, an operating voltage lower bound based on the operating voltage.
