ELECTRIC POWER TRANSDUCER Russian patent published in 2008 - IPC H02H3/08 

FIELD: electricity.

SUBSTANCE: electric power transducer contains current transformer, the primary winding of which is connected between the source of power supply and its load, and the secondary winding through rectifier is connected to condenser and load of transducer. In order to achieve technical result - increase of fast-action and expansion of range of permissible inlet currents of transducer, two thyristors are installed in it, which are connected antiparallelly to the secondary winding of current transformer. The control electrode of every thyristor is connected to anode through sequentially connected diode and stabilitrone. Besides, in order to expand the functional possibilities of transducer, the secondary winding of current transformer is connected to the power supply source through sequentially connected condenser and resistor.

EFFECT: improves fast-action of transducer of electric power and expansion of range of transducer permissible input currents.
