Abstract:
An active preload circuit includes: a rectifier configured to receive an AC input from a TRIAC dimmer and to generate DC power; a preload; and a phase angle controller configured to selectively couple the preload to the DC power.

Claim (Index 2):
The active preload circuit of  claim 1 , wherein the phase angle controller comprises:\n an operational amplifier; a first resistor coupled between a positive terminal of the rectifier and the inverting input of the operational amplifier; a reference voltage coupled to the non-invering input of the operational amplifier; a supply voltage coupled to the positive supply voltage input of the operational amplifier; a second resistor coupled between the inverting input of the operational amplifier and a third resistor; the third resistor coupled between the second resistor and a negative terminal of the rectifier; a capacitor coupled between the inverting input of the operational amplifier and the negative terminal of the rectifier; a zenier diode coupled between the output of the operational amplifier and the negative terminal of the rectifier; a fourth resistor coupled between the output of the operational amplifier and the positive terminal of the rectifier; and a switch coupled between a terminal of the preload and the negative terminal of the rectifier, the gate of the switch being coupled to the output of the operational amplifier, the preload being coupled between the switch and the positive terminal of the rectifier.
