ABSTRACT:
A magnetic amplifier is disclosed which has improved fail-safe characteristics, the amplifier has a pair of saturable magnetizable cores with d.c. control winding turns on each which are mutually decoupled in known manner with regard to input a.c. windings and the a.c. windings also have linked with them a further magnetizable core, the output from the transductor being derived from a secondary winding on the further cores. The arrangement enables various applications of a magnetic amplifier to be made which might otherwise be objectionable by reason of the reduced operational failure-to-safety characteristics. These applications include use in a brake control circuit.
