| Title: |
Methods and Apparatus for High Power Factor Controlled Power Delivery Using a SIngle Switching Stage per Load |
| Abstract: |
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.
