Hello,
I wish to build a "universal light dimmer" meaning the dimmer will be able to support both leading and trailing edge phase control of mains 120V/60Hz. Ideally, i would like the circuit to be able to auto-detect the load type (RLC) and select the appropriate phase control scheme to handle the load.
I know there are commercial dimmers that do this. Does anyone have suggestions? It seems like it would be hard to determine based on the voltage-current phase relationship given that the current will be distorted relative to the line voltage.
Thanks!
