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.

Claim (Index 16):
An inverter circuit comprising:\n a plurality of switches in a power train configured to convert a received dc voltage into a cyclically alternating output voltage; and a controller configured to control the switching state of each of the switches in the plurality of switches, the switching state including switching a pair of the switches consistent with a power line frequency and a pair of the switches at a high frequency, which is ten times or more, faster than the power line frequency, wherein the controller is further configured to operate the switches in multiple switching modes where a first switching mode is maintained during a zero-voltage crossing when a power factor being monitored is in unity, and where a second mode is used when a power factor being monitored is not in unity, wherein the second mode includes a switching state change through a zero-voltage crossing, the switching state change including introducing a short circuit into the switching scheme of the plurality of switches, the short circuit having a duration of Ts, the duration of Ts being set using a measured switching frequency of one or more switches in the plurality.
