摘要：A universal series bus (USB) power supply has a DC power source, a USB powerinterface and a voltage modulation module. The USB power interface is for connecting toan electronic device that stores a default D+ voltage and a default D− voltage. Thevoltage modulation module connects to and outputs signals to the D+ and D− terminals
of the USB power interface. If voltage levels of the output signals are not respectivelyidentical to the default D+ and D− voltages, the voltage modulation module changes thevoltage levels of the signals output to the D+ and D− terminals of the USB powerinterface until the voltage levels of the output signals are respectively identical to thedefault D+ and D− voltages. Therefore, the USB power supply may be applied to anykind of electronic device that is charged over a USB interface.
