Abstract: A system for balancing and converting voltage output from photovoltaic modules includes a set of solar substrings and a power conversion circuit. The power conversion circuit includes a balancing section configured to balance voltage output from the set of solar substrings. The power conversion circuit also includes a voltage control section including: a first transformer coupled to the set of solar substrings and configured to step-up voltage from the set of solar substrings; a second transformer arranged in series to the first transformer; and an output capacitor coupled to the second transformer. The system further includes a controller configured to: drive a set of modulation signals to the balancing section and the voltage control section; alternate voltage polarities across the first transformer and the second transformer; and modify output voltage of the power conversion circuit to a target output voltage.

Abstract: 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.
