AC power conditioning circuit

摘要

A multi-coil choke for an AC power conditioner includes a magnetic core having first, second and third parallel legs. A first coil wrapped around the first leg terminates in first and second leads at respective ends. A second coil wrapped around the second leg terminates in first and second leads at respective ends. A third coil wrapped around the third leg terminates in first and second leads at respective ends. A fourth coil is formed from a proximal portion of the second lead of said first coil. The fourth coil is wrapped around a distal portion of the second lead of the third coil. A fifth coil is formed from a proximal portion of the second lead of the third coil. The fifth coil is wrapped around a distal portion of the second lead of the first coil. AC power conditioners using one or more such chokes are also disclosed.

主权项

1. A multi-coil choke comprising:
a magnetic core having a first leg, a second leg and a third leg, said legs being substantially parallel to each other; a first coil wrapped around said first leg and terminating in a first lead at a first end thereof and a second lead at a second end thereof; a second coil wrapped around said second leg and terminating in a first lead at a first end thereof and a second lead at a second end thereof; a third coil wrapped around said third leg and terminating in a first lead at a first end thereof and a second lead at a second end thereof; a fourth coil formed from a proximal portion of the second lead of said first coil, said fourth coil being wrapped around a distal portion of the second lead of said third coil but not being wrapped around the core; a fifth coil formed from a proximal portion of the second lead of said third coil, said fifth coil being wrapped around a distal portion of the second lead of said first coil but not being wrapped around the core; the distal portion of the second lead of said first coil passes through said third coil before passing through said fifth coil; the distal portion of the second lead of said third coil passes through said first coil before passing through said fourth coil; and said first coil is wrapped in one of a clockwise and counterclockwise direction, and said second and third coils are wrapped in the other of said clockwise and counterclockwise direction.
