Abstract

Inverter circuit operation for managing power factor changes is provided. Various modes of switch timing may be employed near zero-voltage crossings. Inverter switch timing may change during a cycle such that one timing strategy is employed approaching or leaving a zero-voltage crossing while another timing strategy is employed at other times of the cycle.
