Multi-output power supply
First Claim
1. An apparatus for providing power to an electronic device, comprising:
- a power input configured to receive an input voltage from a power supply;
a rectifier operatively connected to the power input and configured to convert the input voltage to a first voltage;
a first power output connector operatively connected to the rectifier, wherein the rectifier is further configured to transmit the first voltage to the first power output connector;
a power converter operatively connected to the rectifier and configured to convert the first voltage to a second voltage different than the first voltage;
a second power output connector operatively connected to the power converter, wherein the power converter is further configured to transmit the second voltage to the second power output connector; and
a first relay operatively connected to the rectifier to selectively prevent the first voltage from being transmitted through the first power output connector,wherein a state of the first relay is determined at least in part by a state of a first control line,wherein the first control line does not transmit the first voltage,wherein the first relay includes a first logic configured to determine whether a first electronic device operatively connected to the first power output connector is compatible with the first voltage.

Abstract
An apparatus for providing power to an electronic device may include a power input configured to receive an input voltage from a power supply, and a rectifier operatively connected to the power input and configured to convert the input voltage to a first voltage. The rectifier may further be configured to transmit the first voltage to a first power output operatively connected to the rectifier. The apparatus may further include a power converter operatively connected to the rectifier and configured to convert the first voltage to a second voltage different than the first voltage and a first relay operatively connected to the rectifier to selectively prevent the first voltage from being transmitted through the first power output. The power converter may further be configured to transmit the second voltage to a second power output operatively connected to the power converter.
