Abstract

An electromagnetic relay adapted to be driven by a.c. voltage includes two windings formed by two wires wound together, each winding having its ends connected through diodes to a respective terminal of the a.c. voltage source. The diodes are connected to each terminal with opposite forward directions so that the magnetic fluxes generated by the two windings have the same direction irrespective of the polarity of the a.c. voltage. The capacity existing between the two windings acts as a reactance for limiting the exciting current without consuming active energy.
