Abstract:
A dimmer includes a power supply circuit including a current limiter and a switch, the power supply circuit electrically coupled to a power source and a load, where current is channeled via the current limiter during a power-on of the dimmer and via the switch during operation of the dimmer after the power-on, a triode for alternating current (TRIAC) control circuit electrically coupled to the power source and the load, where the TRIAC control circuit is structured to control operation of a TRIAC configured to control an amount of power supplied to the load; and a processing unit electrically coupled to the power supply circuit and the TRIAC control circuit, where the processing unit is structured to control the switch and the TRIAC control circuit after the power-on.
