Abstract
A universal serial bus (USB) charging system includes a power supply including a plurality of power converters and a plurality of power supply outputs electrically coupled to the plurality of power converters, respectively. Each of the plurality of power converters is configured to convert an input voltage to a plurality of output voltages. A plurality of charging ports are electrically connected with the plurality of power supply outputs, respectively. Each of the plurality of charging ports is configured to provide an output voltage selected from the plurality of output voltages to an electronic device. A logic circuit is in electrical communication with the power supply and the plurality of charging ports. The logic circuit is configured to provide direct feedback to the power supply to output a particular output voltage of the plurality of output voltages to the plurality of charging ports.
