Abstract
A magnetic amplifier including a magnetic core having a primary leg, a secondary leg, and a control leg. A primary winding is wound about the primary leg of the magnetic core for generating a non-saturating magnetic AC flux in the magnetic core, and a secondary winding is wound about the secondary leg of the magnetic core. A control winding for conducting DC current is wound about the control leg of the magnetic core for controlling as a function of the DC current, without saturating the magnetic core, the reluctance of the control leg relative to the reluctance of the secondary leg. By controlling the relative reluctance, the amount of magnetic AC flux coupled to the secondary winding is controlled, thereby relative reluctance, the amount of magnetic AC flux econtrolling the output voltage provided by the secondary winding.
