Abstract
This article introduces a switched-photovoltaic
(SPV) DC–DC converter that switches the photovoltaic (PV)
cells of a series solar string periodically in parallel to balance
their voltages and extract the maximum available power under
mismatch conditions. Without any assistance from an external
DC–DC converter, the SPV converter exploits the intrinsic
capacitance of the PV cells to establish an implicit 1: n switched-
capacitor (SC) converter that allows the extra current of the
stronger cells in
