Single-ended saturable reactor circuit with quiescent current compensation

This paper has been prepared to introduce a single-ended saturable reactor circuit which exhibits a transfer characteristic for which the d-c output is essentially a linear function of the d-c input for the entire design range of d-c inputs. This “to-zero” operation is shown to be the result of a unique combination of nonlinear characteristics of conventional devices, transformer and rectifier, which eliminates the magnetizing component of the reactor current from the d-c output. The new circuit is presented and a qualitative description of the circuit operation is given.
