SYSTEM FOR BALANCING AND CONVERTING VOLTAGE OUTPUT FOR PHOTOVOLTAIC MODULES

A system for balancing and converting voltage output from photovoltaic modules includes a set of solar substrings, a power conversion circuit, and a controller. The power conversion circuit includes: a set of windings coupled in series and arranged in parallel to the set of solar substrings; a set of switches coupled in parallel and interposed between the set of solar substrings and the set of windings; and an output switch coupled in series to a first switch, in the set of switches, and an output capacitor. The controller is configured to: oscillate states of the set of switches and the output switch at a first duty cycle; balance voltages output from the set of solar substrings across the set of windings to a nominal output voltage; and modify the nominal output voltage to a target voltage directed to the target load based on the first duty cycle.
