ABSTRACT:
An enhanced variable impedance transformer is disclosed for controlling the power from an alternating input power source to a load in accordance with a direct current control signal. The variable impedance transformer comprises a first and a second annular saturable reactor core and an annular power core with a power input winding being simultaneously wound about the annular power core and the first and second annular saturable reactor cores. A power output winding is wound about the annular power core for transferring power to the load. The power input windings are connected to the alternating input power source for establishing a magnetic flux in the annular power core and in the first and second annular saturable reactor cores. A first and a second control winding are respectively wound about the first and second annular saturable reactor cores for controlling saturation of magnetic flux in the first and second annular saturable reactor cores for controlling the power transferred to the power output in accordance with the direct current control signal. The first and second annular saturable cores are disposed in a coaxial relationship with the annular power core being interposed between the first and second annular saturable cores for reducing leakage flux of the variable impedance transformer.
