  • Power converter
    Patent number: 6424548
    Abstract: The present invention relates to a bi-directional AC/DC converter having (i) a power stage, (ii) a sourcing control circuit and (iii) a recuperation control circuit. The converter operates with a Power Factor Correction in both directions, i.e. when transferring energy from the AC mains into the DC load as well as when it is transferring energy from an active DC load into the AC mains. Smooth transition between sourcing and recuperation is possible by allowing an active load to control the output voltage until the correct control circuit begins regulation.
