CONTROL CIRCUIT OF BRIDGE DEVICE THYRISTOR FOR ESTIMATION OF INDUCTION ELECTRIC METERS SUITABILITY Russian patent published in 2016 - IPC G01R11/24 

FIELD: electricity.

SUBSTANCE: invention suggests a control circuit of a bridge device thyristor for the estimation of induction electric meters suitability, it contains in bridge arms storage capacitors, their outputs are connected at one side to grid conductors, and at another side to the thyristor in the diagonal of the bridge device. In series with the storage capacitors power diodes and chokes are connected, they are connected to the grid conductors, and the control circuit of the thyristor contains connected in series a diode, a variable resistor and an additional capacitor, connected in parallel to the cathode and anode of the thyristor, and its control electrode is connected to the connecting point of the variable resistor and additional capacitor through the connected in series diode thyristor and limiting resistor.

EFFECT: device simplification.
