Abstract
Reducing total harmonic distortion of power-factor correction switching converters. At least one example is a method of operating a power-factor-correction (PFC) converter, the method comprising: charging an inductance of the PFC converter, thereby creating a charge mode; asserting, during the charge mode, an initial-reset signal by a reset circuit implementing voltage-mode control; ending the charge mode a compensated time after assertion of the initial-reset signal, the compensated time inversely proportional to a magnitude of an input voltage of the PFC converter; and then discharging the inductance of the PFC converter.
