Patent ID: 7642888

Claim:
A electric reactor of controlled reactive power comprising: a magnetic core having a central column positioned in spaced parallel relation to a pair of external columns positioned on opposite sides of said central column, said magnetic core having a superior yoke connected to one end of said central column and to an end of said pair of external columns, said magnetic core having an inferior yoke connected to an opposite end of said central column and to an opposite end of said pair of external columns, said superior yoke having a first pair of orifices positioned between said central column and one of said pair of external columns, said superior yoke having a second pair of orifices positioned between said central column and another of said pair of external columns; a primary winding concentrically wound around said central column; a first control coil wound through said first pair of orifices; a second control coil wound through said second pair of orifices; a main current supplying means connected to said primary winding for supplying a main magnetic flow in said magnetic core; a control current supplying means connected to said first and second control coils for generating a first magnetic control flow in said magnetic core and for generating a second magnetic control flow in said magnetic core such that said second magnetic control flow has a direction opposite to a direction of said first magnetic control flow and such that said first and second magnetic control flows form a magnetic distortion field, said magnetic distortion field combining with said main magnetic flow so as to cause a change in reluctance of said magnetic core.
