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.
A high-power thyristor.
The power thyristor (10) of the invention has a cellular emitter structure.
The reactive power compensator (1) comprises a thyristor-switched capacitor (6).
The thyristor is configured to control a power level of the one or more heating elements.
The protection device includes a bipolar device or a silicon-controlled rectifier (SCR).
The surge limiter includes a resistor (41) and an SCR (43) connected in parallel between the filter capacitor and a common rail (56).
When SCR (116) fires, the voltage of capacitor (100) supplies a boost of power to motor (106) to overcome the decrease in motor speed.
The discrete semiconductor device can also be a transistor, thyristor, triac, or transient voltage suppressor.
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.
An integrated power switch structure comprises a lateral MOS transistor (3) and a lateral or vertical thyristor (2).
A thyristor axis (222) lies perpendicular to the thyristor plane.
In addition, in the case of thyristor over-current, which may indicate that both power thyristors (11, 12) are conducting at the same time, the power thyristors are commutated.
The bus voltage signal detected by the bus voltage detection circuit is transmitted to the power microprocessor, the output of which is transmitted to the thyristor driving circuit controlling the thyristor rectifying circuit.

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.
A thyristor has a thyristor structure produced in a semiconductor body (1).
The incorporated auxiliary thyristor system is always triggered before the main thyristor system.
The operation of the power thyristor is controlled on the basis of transistors VT1 and VT2.
With the development of power electronics technology, a thyristor inverter intermediate frequency power supply has been used.
The thyristor triggering and monitoring unit generates and sends a triggering pulse to a thyristor gate pole.
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.
If the thyristor isn't triggered in time, the thyristor may be probably damaged.
