A thyristor axis (222) lies perpendicular to the thyristor plane.
The auxiliary thyristor trips before the main thyristor and provides a current with steep rise slope which contributes to the uniform energization of the main thyristor.
If the thyristor isn't triggered in time, the thyristor may be probably damaged.
A thyristor has a thyristor structure produced in a semiconductor body (1).
The invention concerns a dual thyristor, a dual diode thyristor, a component forming a thyristor and a component forming a diode thyristor, a power converter and a switch provided with one or the other among same.

The discrete semiconductor device can also be a transistor, thyristor, triac, or transient voltage suppressor.
The separate zener diode (56) is also electrically connected between the gates of the SCR at the one end (60) and the next adjacent SCR (54).
A transistor circuit controls the triggering of the SCR, and is adapted to turn the SCR on in response to a voltage surge on the first voltage supply terminal.
The anode of the thyristor (SCR) is connected to an alternating current input terminal (ACIT) and the cathode of the thyristor (SCR) is connected to a load terminal (LDT).
An SCR (7) is connected between the output terminals of the converter.
Said half-controlled three-phase diode-tyristor rectifier unit (1) comprises a resistor (6) which is in series connected to the tyristor (4).
Thyristor SGCT (Symmetric Gate-Commutated Thyristor) with integrated gate driver
Methods and systems consistent with this invention detect a voltage across the thyristor, and indicate a failed open thyristor when the absolute value of the voltage across the thyristor exceeds a threshold value.
In a triggering interval, the forward voltage of the thyristor reaches +100V, and the thyristor is retriggered automatically, thereby the safe and reliable operation of the thyristor and the system are ensured.
If the current of both terminals of the thyristor becomes discontinuous suddenly, the current crosses zero, thereby the thyristor is turned off.
The thyristor triggering and monitoring unit generates and sends a triggering pulse to a thyristor gate pole.
A semiconductor controlled rectifier for an integrated circuit is disclosed.
All these perimeter zones (42-44) together provide the thyristor with a deep peripheral termination which surrounds the active thyristor area (Aa).
A thyristor is coupled to the electrical heating elements.
In the event of an overvoltage, the Zener diode conducts and establishes a trigger current for the auxiliary thyristor and the main thyristor.
These active shunts are inactive until after the thyristor is turned off.
A high-power thyristor.
The switching device (40) may include a GTO thyristor, a MOS controlled thyristor, or combinations thereof with conventional thyristors.
The driving circuit comprises a first thyristor, a first current-limiting resistor, a first resistor, a thyristor switch, and a control circuit.
