Abstract
A power supply system and method are disclosed. The power supply system is to generate a power signal for providing power to a device. The power supply system includes a transmitter to modulate a data signal onto the power signal that is demodulated at the device. The transmitter is further to transmit a separate binary control signal on the power signal to change a state of a digital control parameter associated with the device.

A power supply system to generate a power signal for providing power to a device, the power supply system comprising a transmitter to modulate a data signal onto the power signal that is demodulated at the device, the transmitter being further to transmit a separate binary control signal on the power signal to change a state of a digital control parameter associated with the device.
A method for providing digital communication in a power system, the method comprising:
- providing a power signal to a device;
- modulating a data signal onto the power signal as a stream of data bits;
- interrupting the stream of data bits to modulate a single-state binary control signal onto the power signal;
- demodulating the data signal at the device;
- and
- changing a state of a digital control parameter at the device in response to the single-state binary control signal.
A power distribution system comprising:
- a power distribution unit to generate a power signal for providing power, the power supply comprising a transmitter to modulate a data signal and a binary control signal onto the power signal;
- and
- a plurality of devices to receive the power signal, each of the plurality of devices comprising a receiver that is to demodulate the data signal and the binary control signal, each of the plurality of devices being further to change a state of a digital control parameter in response to the binary control signal.
