Zusammenfassung:	Methods and apparatus to improve power factor are disclosed. An example method includes detecting power provided to a power factor corrector; detecting power provided by the power factor corrector; and disabling the power factor corrector from correcting a power factor of a load for at least one period when the power provided by the power factor corrector is below a light-load threshold.
