Triggering board for Thyristors

COUGAR ELECTRONICS has a full range of triggering boards for thyristors press pack applications.

ARCTI CP - 3kV insulation

The ARCTI-CP board enables to dispatch control pulses to 2 thyristors. A pulse transformer ensures the isolation between the power and the control and between the 2 outputs.

ARCTI CP4 - 10kV insulation

The ARCTI-CP3 board enables to transmit control pulses to a high power Thyristor.
A pulse transformer insures the 10kV insulation between the power and the control command.
The low leakage inductor of the transformer makes it possible to get a di/dt compatible with most of high power Thyristors.
We can use benefits of the product Ut of the pulse transformer due to the top value of current on the primary of the transformer.

ARCAP 50 - Phase angle thyristor control module

The ARCAP-50 is a universal phase angle control module. It enables to drive up to 2 thyristors and is suitable for all types of assemblies: rectifiers, power controllers or switch gates, one, two or three-phase. No configuration needed. The synchronization is automatically done on the input voltage of the converter. There is thus no need to set the phase difference or the tracking of the phase order.

  • High levels of insulation
  • Network voltage from 48Vac to 400Vac
  • Power supply from 12 to 24Vdc
  • Progressive starting
  • Up to 1A peak per output
  • 0-10V and 0-20mA control

FART 4 - Trigger for switch gates

The FART4 module enables to trigger switch gates (2 head-to-foot thyristors) from a 0-10V or 0-20mA control command.

  • Insulation : 3500Vac
  • Input 0-10V and 0-20mA
  • Detection of zero-crossing
  • State display
  • Standard housing

Triggering Boards for Thyristors

The technology

Selenium rectifiers and suppressors are still used in the industry for their strong reliablity. This technology has been mainly replaced by silicon diodes, providing a better efficiency and lower voltage drop. Selenium components are very interesting for their reliability. Those components have the ability to recover after surge failure, which make them excellent for security applications. COUGAR ELECTRONICS has been one of the leading company in the 50's. We are the last firm still manufacturing parts made in USA thanks to our CT factory.

Elevator industry, Military and power generation

Despite most of our business is now focused on up to date semionductors like silicon diode, thysirtors, IGBT and SiC, our manufacturing department is serving elevator industry (otis, schindler, kone, thyssen krupp). We also serve specific fields like military or power generation application .

Troubleshooting a selenium rectifier or suppressor

Our customer service will be happy to help you to determine what's the best solution.

Find parameters for rectifiers :

  • Voltages: Standard Voltages per cell up to 36 v rms. The voltage rating is determined by the number of cells in series
  • Current: Ratings are determined by the size of the cell or the number of cells in parallel. The circuit configuration and the type of cooling are also important factor to consider.
  • Circuits: Half wave, Doublers, Center Taps, Full Wave Bridges, single and three phase.

Find parameters for suppressors :

  • Ratings: Determined by the cell size and number of cells in a series (similar to rectifiers above).
  • Suppressors are also rated by the voltage clamping factor and the amount of reverse energy they can absorb (in joules).
