Abstract: A direct-current converter, for isolating a measuring transducer from its power source, comprises a magnetic core with primary, secondary and sensor windings. Additionally an energizing winding is provided periodically to change the magnetic inductance of the core, by developing a magnetic field at right angles to that of the other three windings.
