18 Claims

1. An electric load controller apparatus, comprising:

a controllably conductive device to adjust power delivered to an operatively coupled electric load device;

electric load controller control circuitry operatively coupled to the controllably conductive device; and

driver communication circuitry communicatively coupled to the electric load controller control circuitry, the driver communication circuitry including:

an input to receive an output signal from the electric load controller control circuitry; and

an output to provide a control signal to the electric load device;

wherein the driver communication circuitry to:

generate the control signal using the received output signal;

sample the generated control signal;

communicate the sampled control signal to the electric load controller control circuitry;

wherein the electric load controller control circuitry to:

receive an input to provide power to an operatively coupled electric load device; and

responsive to receipt of the input to provide power to the electric load device:

transition the controllably conductive device to a CONDUCTIVE state;

detect whether the electric load device generates a link supply voltage responsive to the provision of power to the electric load device;

determine whether the detected link supply voltage is at or above a threshold value; and

responsive to the determination that the link supply voltage is at or above the threshold value:

transition the electric load controller to a NORMAL state; and

adjust the output signal to control the power delivered to the electric load device based on the sampled control signal.
