Patent number: 12107417Abstract: A system and method for combining power from DC power sources. Each power source is coupled to a converter. Each converter converts input power to output power by monitoring and maintaining the input power at a maximum power point. Substantially all input power is converted to the output power, and the controlling is performed by allowing output voltage of the converter to vary. The converters are coupled in series. An inverter is connected in parallel with the series connection of the converters and inverts a DC input to the inverter from the converters into an AC output. The inverter maintains the voltage at the inverter input at a desirable voltage by varying the amount of the series current drawn from the converters. The series current and the output power of the converters, determine the output voltage at each converter.Type: GrantFiled: October 11, 2017Date of Patent: October 1, 2024Assignee: Solaredge Technologies Ltd.Inventors: Meir Adest, Lior Handelsman, Yoav Galin, Amir Fishelov, Guy Sella
