Abstract
A constant-voltage transformer for stabilized power supply includes a primary coil and a secondary coil connected across a tuning capacitor. A magnetically continuous magnetic core links both the primary coil and the secondary coil, and a magnetically discontinuous magnetic core links the secondary coil but not the primary coil. Another discontinuous magnetic core may link the primary coil but not the secondary coil, and a compensating coil may be linked by this core only. Preferred designs have an abrupt cut-off at a load current only a little greater than design value, so that a dangerously high current can never be drawn, even into a total short circuit.

A constant-voltage transformer comprising a primary coil, a secondary coil, a tuning capacitor connected across said secondary coil, a magnetically continuous magnetic core linking both said primary coil and said secondary coil, a magnetically discontinuous magnetic core linking said secondary coil but not said primary coil and another discontinuous magnetic core linking said primary coil but not said secondary coil.
A constant-voltage transformer comprising a primary coil, a secondary coil, a tuning capacitor connected across said secondary coil, a magnetically continuous magnetic core linking both said primary coil and said secondary coil, a first magnetically discontinuous magnetic core linking said secondary coil but not said primary coil, and a second discontinuous magnetic core linking said primary coil but not said secondary coil, each said magnetic core being formed of curved laminations of grain-oriented material.
A constant-voltage transformer comprising a primary coil, a secondary coil, a tuning capacitor connected across said secondary coil, a magnetically continuous magnetic core linking both said primary coil and said secondary coil, a first magnetically discontinuous magnetic core linking said secondary coil but not said primary coil, a second discontinuous magnetic core linking said primary coil but not said secondary coil, and a compensating coil linked by said second discontinuous magnetic core only and connected in series with at least part of the secondary coil.
