First Claim
1. A method of providing power to a plurality of light emitting diodes of a circuit, the method comprising:
- energizing a first secondary module and a second secondary module from a transformer of a primary module;
energizing a first light emitting diode by the first secondary module, wherein the first light emitting diode is coupled in series with the first secondary module; and
energizing a second light emitting diode by the second secondary module, wherein the second secondary module is coupled in series with the first light emitting diode and the second light emitting diode, and wherein the circuit is configured to flow a direct current from the second secondary module to the first secondary module and back to the second secondary module;
wherein the first secondary module is configured to have a first voltage polarity, and wherein the first load is configured to have a second voltage polarity opposite the first voltage polarity.

Abstract
An apparatus and computer readable storage medium are disclosed for supplying power to a load such as a plurality of light emitting diodes. A representative apparatus comprises a primary module, a first secondary module couplable to a first load, and a second secondary module couplable to a second load. The primary module comprises a transformer having a transformer primary. The first secondary module comprises a first transformer secondary magnetically coupled to the transformer primary, and the second secondary module comprises a second transformer secondary magnetically coupled to the transformer primary, with the second secondary module couplable through the first or second load to the first secondary module.
