Abstract:
Programmable drivers (or power supplies) for solid state light sources are disclosed, on which output regulation is improved to expand the dimming range to 1% and reduce and/or remove flicker. Additional fault conditions are set up to avoid latching, and thus provide for a controllable restart feature. Such drivers include an isolated half bridge resonant converter with an improved control approach designed to regulate very low current though primary side in a feed-forward loop. Such drivers include both digital and analog loops that improve the performance in steady state and/or during transients, particularly for a lighting load, in comparison to a single full digital control.

Claim (Index 5):
The regulation circuit of  claim 1 , wherein the feedback loop comprises:\n a Proportional Integral Derivative (PID) digital control programmable set point having a current sensing input capable of electrical communication with a first lead of a load, a voltage sensing input capable of electrical communication with a second lead of the load, a connection to an isolated ground, a user setting input, and an output; a second series resistor having a first lead connected to the output of the PID digital control programmable set point, and a second lead; an opto-coupler having a first input connected to the second lead of the second resistor, a second input connected to the isolated ground; a third input, and an output; a pull-up resistor having a first lead connected to a reference voltage, and a second lead connected to the third input of the opto-coupler; a filter having a first input connected to the output of the opto-coupler, a second input connected to ground, and an output; and a third series resistor having a first lead connected to the output of the filter and a second lead comprising the second output of the feedback loop.
