Abstract:
1. A load control device for controlling the amount of power delivered to an electrical load from an AC power source, the load control device comprising: a controllably conductive device adapted to carry a load current from the AC power source to the load when the controllably conductive device is conductive; a power supply comprising an energy storage device and adapted to charge the energy storage device when the controllably conductive device is non-conductive; and a controller operable to determine when the power supply has charged the energy storage device to a predetermined amount of energy and to subsequently cause the controllably conductive device to become conductive immediately after determining that the power supply has charged the energy storage device to the predetermined amount of energy; wherein the power supply comprises a passive charging path for the energy storage device, and an active charging path for the energy storage device, the passive charging path allowing the energy storage device to receive energy at a first rate, the active charging path allowing the energy storage device to receive energy at a second rate greater than the first rate.
