THYRISTOR CONTROL CURRENT PULSE FORMER Russian patent published in 2013 - IPC H02M1/08 H02M1/14 H02M1/36 H03K17/424 H03K17/08 

FIELD: electricity.

SUBSTANCE: pulse former has a controlled source of pulse signals of a control system of a converter, a double-wire line for transmitting the control signal, a controlled former of rectangular voltage pulses, a unit for converting the shape of voltage pulses, an operational amplifier, resistors, a transistor, a pulse transformer, a diode and a dc voltage source. The controlled source of pulse signals of the control system of the converter is based on a current source circuit, a voltage level limiter, a trigger pulse former, an electronic switch, an electronic switch control pulse former, a separating capacitor, connected to each other according to the claim.

EFFECT: high noise immunity of the thyristor control current pulse former.
