Systems and methods described herein provide for high speed power factor correction which can overcome or substantially alleviate the problems associated with changes in the operating conditions of a load or other transient events. The present technology senses the present state conditions of a signal to quickly and accurately determine the presence of an overtone component within the signal. The expected value of the overtone component is then determined based on the sensed state of the signal. Power factor correction is then performed to suppress the overtone utilizing a control signal formed based on the expected value of the overtone. By performing power factor correction based on the expected value, the present technology can provide high speed power factor correction which is not limited by the delay introduced by an adaptive feedback loop.
