Abstract
A wide range voltage regulator circuit exhibiting minimum circuit impedance at maximum output voltage employs a pair of regulating windings in series having their movable contact controlled by a plurality of normally open and normally closed limit switches. The extreme stationary contacts within the first regulating winding are connected with the movable contacts within the second regulating winding to provide a wide range of voltage regulation with negligible impedance at the maximum voltage position.

A voltage regulator comprising:
- a first series winding arranged around an associated electromagnetic core and connected at one end to a first terminal;
- a plurality of first tap windings within said first winding;
- a plurality of first stationary contacts connected with each of said first tap windings;
- a first movable contact for making contact with each of said first stationary contacts and with a second terminal for varying voltage output at said second terminal;
- a second series winding electrically connected with said first series winding;
- a plurality of second tap windings within said secondary winding;
- a plurality of second stationary contacts connected with said second tap windings;
- a second movable contact for making contact with each of said second stationary contacts;
- and
- an exciting winding wound around an associated electromagnetic core and connected with said second series winding and a third terminal, said third terminal providing a common connection between a voltage source and a voltage load.
