APPLIANCE AC POWER CONTROL APPARATUS

摘要

An apparatus (90) for controlling an electrical appliance coupled with an output terminal and configured to operate in response to an alternating input signal, such as input AC power. The apparatus comprises a reference signal generator (96) for receiving the input signal and generating a reference signal (either Vramp of Vcontrol) in response to the input signal, and a control circuit (104) for controlling connection of the input signal to the output terminal in response to the reference signal and to a user-defined setpoint signal.
