Fast Switching Thyristors 250A – 3200A, Disc Package

Fast Switching Thyristor AS ENERGITM in disc design, also called "Fast Impulse Thyristor" (TFI) is a press pack type fast switching semiconductor device. Fast switching 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 3200A at frequency range is up to 10kHz in circuits with voltages to 4000V (depending on series).

Power disc fast switching (pulse) thyristors series TFI have the following types (current): 250 A, 320 A, 400 A, 500 A, 630 A, 800 A, 1000 A, 1250 A, 1600 A, 2000 A, 2500 A, 3200 Ampere.

Installation recommendations for fast switching thyristors

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.

Installation recommendations for fast thyristors:

Assembling disc fast thyristor with a heatsink

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.

Device under voltage

It is strictly forbidden to touch power thyristors under high voltage during operation.

I'm Gizem, I'm a chemical engineer. I'm interested in making ceramic stuffs as a hobby. Would you please give some explanation about my questions below;
1) If I only mix SiO2 and Fe2O3 (3:1), can i get a suitable product without using other components?
2) Can i use water as fastener? or would you suggest me another fastener?
3) At which temperature should i mix them?
Thank you for your interest, Kind Regards

Hello, Gizem. The mass of ceramic is produced by grinding and mixing with water of different components: clay, feldspar, sand, kaolin. The proportions of these materials are different percentages, depending on what and with what characteristics you need to get a ceramic mass.
Each manufacturer of ceramic mass has its own recipes and its own raw materials, which are available in its region.
There are also books on ceramics that specify the chemical composition and approximate recipes for ceramic masses.

Is It need to apply vaselin or thermal past at Thyristor surfaces then attach to radiator/current leading parts?

When assembling thyristors, diodes with heat sinks, it is recommended to lubricate the contact surfaces with a thin layer of heat conducting paste to improve the heat transfer parameters. But this is not a prerequisite for assembly.
