Abstract
A multi-port charging system includes a controller having a power input terminal coupled to a DC power output of a converter, multiple power output terminals coupled to the power input terminal, and a communications input terminal. The system includes multiple charger ports, the respective charger ports having a charging power line coupled to a respective one of the power output terminals, and a communications line coupled to the communications input terminal. The controller is configured to control the state of the control output terminal to set a voltage of the DC power output according to a selected highest common compatible voltage of one or more sink devices coupled to one or more respective ones of the charger ports.
