Saturable Reactor Inductors

Osborne Saturable Reactors are designed to provide a variable output voltage through the use of variable impedance connected in series with a constant impedance load. Each saturable reactor’s impedance is determined by the application of DC power to a control winding. As the level of power supplied to the control winding is increased, the saturable reactor becomes more saturated. This reduces the impedance of the AC gate winding, and increase the amount of the supply voltage that is transferred to the load. Conversely, as the power is reduced to the control winding, the reactor becomes less saturated, the gate winding has more impedance and less of the input voltage is provided to the output impedance. This approach provides excellent quality, reliability, and control when designed to match the requirements of a specific application.
