The Analysis and Design of Constant Voltage Regulators
I. Friedman · IRE Transactions on Component Parts · 1956
This paper is concerned with analysis and with the development of method for designing constant voltage regulators. A constant voltage regulator will give a more nearly constant output voltage regardless of a limited input variation. This type of regulator consists of an input inductor, a transformer, and condenser connected as shown in Fig. 1. The series inductor resonates with the capacitance and drives the voltage across the transformer into saturation. The current limiting effect of the series inductor plus the saturation of the transformer results in a measure of regulation.
