Abstract

See full text

In one embodiment, a power factor correction ('PFC') circuit is adapted to readily being retrofitted to existing power supplies, provided with new power supplies and/or integrated into new power supplies. The PFC circuit, unlike prior circuits, is connected in parallel with a power supply rectifier such as an AC-DC rectifier. In one embodiment the rectifier is a bridge rectifier with a rectifier-fed capacitive primary energy reservoir being used as an electrical power source. In one embodiment of the invention, the PFC circuit uses a boost converter governed by a control system to provide a cycle-completion, current-filling PFC mode above a prescribed average power threshold, and a continuous cycle PFC mode below the prescribed average power threshold.
