Claim:
1. An apparatus including at least one alternating current (AC) power controller, the AC power controller comprising: a line coupled capacitor AC to direct current (DC) converter circuit to obtain power from an alternating current (AC) power line selectively coupled to a load; a communication circuit supplied with power from the capacitor AC to DC converter circuit to transmit or receive information associated with one or more aspects related to power supplied to the load; and a secondary AC to DC power supply circuit to supply power for use by the AC power controller, the secondary AC to DC power supply circuit supplying more power than the line coupled capacitor AC to DC converter circuit; wherein the AC power controller utilizes power supplied by the line coupled capacitor AC to DC converter circuit in a first power state while the communication circuit waits for a command to supply power to the load and the AC power controller utilizes power supplied from the secondary AC to DC power supply circuit in a second power state while power is being supplied to the load, the second power state utilizing more power than the first power state.
