Patent ID: 8604709

Claim:
A method of using pulses of fixed duration and fixed frequency for power control of electrical loads, the method comprising: with a processing system, providing a timing signal to a circuit, wherein the timing signal includes an ON state and an OFF state; determining a desired power level for an electrical load in the circuit; based on the timing signal, generating a control signal including a sequence of control pulses of fixed duration and fixed frequency within the timing signal and corresponding to the desired power level; and supplying the control signal to an input of a current switch connected to the electrical load, in the circuit, to place the switch in one of an ON state during each pulse and an OFF state after each pulse to cause current to flow from a first potential to a second potential through the electrical load during the ON state; wherein the circuit has an initial condition before flow of current through the current switch and the period time between each of the pulses of the timing cycle is longer than the period of time for the circuit to return to the initial condition after a pulse of the timing cycle.
