  • Low loss recirculation apparatus
    Patent number: 5508906
    Abstract: A low loss recirculation apparatus for recirculating current through an inductive load (101) includes an active recirculation circuit. The low loss recirculation apparatus includes a control device (201) with a drive output (203) that provides a drive signal (205), and a recirculate output (207) that provides a recirculation signal (209). A device (103) provides drive current, along a path (109), to the inductive load (101) responsive to the drive signal (205). A gated recirculation circuit (202), recirculates current, along a path (115), through the inductive load (101) responsive to the recirculation signal (209).
