SOLAR CHARGE CONTROLLER ADAPTABLE FOR MULTIPLE SOLAR SUBSTRING CHEMISTRIES AND CONFIGURATIONS
DRIVE
March 31, 2022
A system for balancing voltages in solar substrings in a first solar panel includes an inductive balancer circuit. The inductive balancer circuit includes a first power level pair and a second power level pair each coupled to the solar substring, and including: a pair of switches arranged in series; a pair of capacitors arranged in series and connected in parallel to the first pair of switches; and an inductor arranged between the first pair of switches and the first pair of capacitors. The system further includes a controller coupled to the inductive balancer circuit and configured to: oscillate states of the pair of switches at a duty cycle; balance voltages across the first power level pair and the second power level pair; and generate a total voltage output that is a multiple of a nominal operating voltage of a most-illuminated solar substring.
