Abrégé
(EN)



Methods and apparatus for high power factor power transfer to a load using a
single switching stage. In exemplary implementations, a controllable variable
power may be delivered to a load using a single switching stage while
maintaining high power factor, in some cases without requiring any feedback
information relating to the load conditions (i.e., without monitoring load
voltage and/or current) to control normal switching operations in the single
switching stage, and without requiring regulation of load voltage and/or load
current. In one example, a single stage high power factor driver is used to
control power delivery to an LED-based light source.
