METHODS AND APPARATUS FOR HIGH POWER FACTOR CONTROLLED POWER DELIVERY USING A SINGLE SWITCHING STAGE PER LOAD |
摘要 |
<p>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.</p> |
