Adaptive current limit for power factor correction |
摘要 |
In one embodiment, an apparatus for performing power factor correction is provided. A power factor corrector includes an input configured to sense a current from an input circuit. A reference generator generates a current limit based on an input voltage. The current limit reference is dynamically changed based on the input voltage. A control signal generator controls the current in the input circuit based on a comparison of the current and the generated current limit. |
