Fast switching thyristors are thyristors with additionally normalized reverse recovery charge Qrr. These devices are adapted for switching current pulses with a high rate of rise at the front and high amplitude. Fast thyristors are devices with reduced tq, trr, Qrr, ERQ values designed to operate at higher frequencies modes. The thyristor parameters of VTM, tq, Qrr are interconnected, so a decrease in the value of tq and Qrr leads to an increase in VTM. Fast switching (pulse) thyristors are characterized with a very low turn-off time and higher value (diT/dt)cr (to 2500 A/µs) that sets them apart from the standard models. They are used in welding, induction heating and melting, electric transportation, AC drives, UPS, and other systems requiring short turn-on and turn-off times. The thyristors have an industry-standard ceramic sealed housing isolating the functional part and the semiconductor element from mechanical impacts and environment. The polarity of the thyristor is determined by the icon on the case. On this page are schematic diagrams and circuits of fast switching thyristors with Anode, Cathode, and control electrode (Gate). The technical specifications, part numbering guide, polarity, dimensions and recommended coolers for thyristors are listed below. Air and water heat sinks are used to cool the thyristors. To keep electrical losses to a minimum and heat dissipation to a maximum, the necessary torque must be provided during assembly, the so-called pressing force Fm. Correspondence of the achieved clamping force to the required one is determined by the deflection of the traverse. For better heat dissipation of discrete thyristor during assembly, heat conducting paste is used, which is not a prerequisite for installation. The fast pulse thyristors have a sealed housing isolating the functional part and the semiconductor element from mechanical impacts and environment. This fast thyristor has a disc housing with pressure contacts. Fast turn-off thyristors from AS Energi Global LLC have the following features: low static and dynamic losses, high values of VDRM/VRRM, extensive experience of using the devices in various industries, range of voltages from 300 to 4000 V and amperages from 250 to 3200 A, high resistance to thermal and electric cycling, natural or forced air cooling. Our company provides a quality guarantee for thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide quality declaration and certificate of conformity. The final price of fast thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
