System for balancing and converting voltage output for photovoltaic modules

A power conversion circuit comprising:

• a set of power level segments, each power level segment in the set of power level segments comprising:
• a winding arranged in parallel with a solar string in set of solar strings;
• and
• a switch arranged between the winding and the solar string;
• an output power level segment comprising:
• an output switch arranged in series with a switch of a power level segment in the set of power level segments;
• and
• an output capacitor connected to the output switch and configured to couple to a load.

A system comprising:

• a set of windings arranged in parallel with a set of solar strings;
• a set of switches interposed between the set of solar strings and the set of windings;
• an output switch coupled in series to a first switch in the set of switches;
• an output capacitor coupled to the output switch and configured to supply energy to a load;
• and
• a controller configured to:
• drive a modulation signal to the set of switches to induce a balanced voltage across the set of windings based on voltages output by the set of solar strings;
• and
• drive a second modulation signal to the output switch to drive the balanced voltage to a target output voltage at the output capacitor.
