ABSTRACT:
The saturable reactor employs two dual drum cores having two winding portions which are sandwiched by two common permanent magnets to statically bias the magnetism. Each winding portion of each drum core is wound with two impedance coils which are individually series-connected to the either of two horizontal deflection coils. Two drum cores are inserted into the common control coils. When a horizontal deflection current is supplied to the impedance coils and a vertical deflection current is supplied to the control coil, the current which flows in a pair of horizontal deflection coils varies differentially in a vertical deflection cycle to minimize misconvergence.
