ABSTRACT:
A method of providing power to an electronic circuit in a two wire dimmer connecting a hot line of an AC network to a lamp load, the method comprising obtaining power from the two wire dimmer during regions of an AC waveform formed across a portion of a circuit of the dimmer when a phase cut switching device of the dimmer providing power to the lamp load is substantially off; driving a switching device providing charging current to a charge storage capacitor on in a saturated region of operation of the switching device when a voltage from a voltage source developed in the dimmer from the AC waveform is less than a predetermined level, and turning the switching device off when the voltage is above the predetermined level; and providing a voltage across the charge storage device as an output voltage.
