UNIVERSAL DC POWER
First Claim
1. A DC-powered device requiring DC power, comprising:
- a device controller circuit for communicating a request for DC power; and
first and second conductors for connecting the DC-powered device to a power converter, wherein the first conductor provides a path for the DC-powered device to communicate the required DC output power to the power converter and for the power converter to supply the required DC output power to the DC-powered device, and the second conductor provides a common reference for conducting return current to the power converter.

Abstract
A power converter capable of providing a range of DC voltages to an external device and a method of providing a range of DC power are provided. The power converter comprises a supply circuit for receiving a request for DC power and for providing the requested DC power. The supply circuit comprises a detection circuit for sensing a connection to an external device, a source controller circuit for determining a DC output power required by the external device, and a converter circuit for generating the required DC output power. The external device comprises a device controller circuit for communicating the request for DC power. A first conductor provides a path for the device to communicate the required DC power to the power converter and for the power converter to supply the required DC power. A second conductor provides a common reference for conducting return current to the power converter.
