Abstract

A power supply, such as for powering and supplying communication data to devices connected with a low voltage line, is disclosed. For example, a converter device is coupled with an alternating current voltage source. The converter device dow n- converts an alternating current voltage to a direct current voltage. A switching device is in communication with the converter device. A processor is in communicati on with the switching device. The processor outputs a signal to the switching device . The switching device generates a square wave signal as a function of the signal from the processor and the direct current voltage. A remote device is controlled by data encoded in the square wave signal.

Claims (20)

1. A power source comprising:
a converter operable to convert a line voltage to a DC voltage;
a switching circuit powered by the DC voltage; and a processor operable to communicate a data encoded signal to the switching circuit, wherein the switching circuit modulates the DC voltage with the data encoded signal to produce an output voltage for powering a remote device and controlling operations of the remote device.
2. The power source of claim 1, wherein the converter, the switching circuit, and the processor are part of a power supply for a low voltage outdoor lighting system.
3. The power source according to claim 1, wherein the output voltage corresponds to an AC voltage with a positive cycle, negative cycle, and an intermediate platform.

6. The power source according to claim 5, wherein a slope of a rising edge of the square wave pulse and a slope of a falling edge of the square wave are controlled so as to minimize spurious emissions.
7. The power source according to claim 6, wherein information is communicated to the power source from the remote device by inserting a pulse during a time associated with the intermediate platform.
8. The power source according to claim 1, wherein the switching circuitry corresponds to a half-bridge circuit.
9. The power source of claim 1, wherein the remote device corresponds to a light device that is part of a low voltage lighting system.
10. The power source according to claim 1, wherein the line voltage is approximately 110 V RMS.
11. The power source according to claim 10, wherein a lowest frequency of the line voltage is approximately 60 Hz.
12. The power source according to claim 10, wherein a lowest frequency of the line voltage is approximately 50 Hz.
13. The power source according to claim 1, wherein the line voltage is approximately 220 V RMS.
14. The power source according to claim 13, wherein a lowest frequency of the line voltage is approximately 50 Hz.
15. The power source according to claim 13, wherein a lowest frequency of the line voltage is approximately 60 Hz.
16. The power source according to claim 1, wherein a peak amplitude of the output voltage is approximately equal to the DC voltage.
17. The power source according to claim 1, wherein the DC voltage is approximately 12V.
