Pavlo GorkunFast Power Thyristors 200A – 2000A, Disc Package
Fast Thyristor (TF) AS ENERGITM in disc design is a press pack type fast switching semiconductor device. Fast thyristors meet requirements, such as increased di/dt resistance, low switching losses, short turn-on and turn-off time. Regulating and converting DC and AC currents to 2000A at frequency range is up to 10kHz in circuits with voltages to 3600V (depending on series).
Power disc fast thyristors series TF have the following types (current): 200 A, 250 A, 320 A, 400 A, 500 A, 630 A, 800 A, 1000 A, 1600 A, 2000 Ampere.

Part numbering guide for power disc fast thyristors
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 thyristors are characterized with a very low turn-off time 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 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 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 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 3600 V and amperages from 200 to 2000 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.

Installation recommendations for fast thyristors:
The reliability of heat transfer and electrical contact between the mating surfaces of the thyristor and the cooler over the entire temperature range is ensured by appropriate torque (clamping force).
Before assembly you should perform visual inspection (1) contact surfaces for mechanical damages and wipe (2), soaked with alcohol (toluene, gasoline, acetone).
After inspection, fix the current contacts (leads), install a pin to fix the alignment of the structure.
To improve the parameters of heat transfer it is recommended to lubricate (3) a thin layer of silicone thermal conductive paste before the assembly, which is not a mandatory condition for installation.
Install the thyristor (3), the second part of the cooler, the fiberglass insulator and the thrust washer.
To thread the traverse (4) and evenly tighten the nuts. Make sure no misalignment and evenness of the contact surfaces.
When the parts are sufficiently clamped but moveable, we recommend placing the cooler on a flat surface and checking the tolerance for parallelism of the overall adjacent plane of the surfaces (5).
Clamp each nut in turn (about a quarter turn) to the stop (6). The amount of deflection of the traverse determines whether the achieved clamping force corresponds to the required one.
After installation, the fasteners (nuts and washers) must be additionally secured against corrosion.
Tips and recommendations for power thyristors:
The power thyristors should not be operated for long periods of time at their limit load for all parameters. In this case, the safety factor is determined by the required degree of reliability of the device.
Replace a failed power thyristor with a thyristor that matches the parameters of the one being replaced.
Supercooling must be provided when operating in an environment with an elevated ambient temperature.
Periodic cleaning of power thyristors and coolers to remove dust and contaminants is recommended to ensure proper heat dissipation.
Inductive current dividers (often twisted toroidal wire) should be used to equalize currents between power thyristors connected in parallel. The most popular connection methods are closed circuit, common coil circuit, or power thyristor. The efficiency of current dividers in this case is determined by the cross section of the magnetic wire.
Prevention of voltage unbalance when power thyristors are connected in series is achieved by using shunt resistors connected in parallel with each thyristor. Voltage equalization in transient conditions is provided by connecting capacitors in parallel to each thyristor.
It is strictly forbidden to touch power thyristors under high voltage during operation.
