A Transductor regulator for stabilized power supplies

A new form of transductor regulator is described which is principally intended for use in voltage-stabilized power supplies delivering output currents of ¿1 A. Better efficiency and reliability is obtained than is usually possible with the conventional series-valve regulator, and the complete power supply can also be physically smaller. The transductor circuit is unusual in that full-wave operation is obtained with a transductor having only one core and, in the simplest case, only one winding. A definite limit exists, however, to the range of regulation that can be obtained. The relatively slow response of the transductor generally necessitates the incorporation of a valve regulator to deal with rapid disturbances; such a regulator, working under Class-B conditions for high efficiency, is also described. Details of a complete power supply embodying both regulators are given, and a simpler power supply using only the transductor regulator is briefly discussed.
