Diode/Thyristor Stacks Benefits

The SEMISTACK CLASSIC family offers a pre-qualified power assembly ready for integration following rigorous SEMIKRON qualification tests and current environmental standards. The platform design has been optimized to achieve the best balance between costs and performance for power inverters and rectifiers as far up as the megawatt range.

Diode/Thyristor Stacks Key Features

  • Various topologies (B6U, B6C, B2C, B2U, W3C, W1C)
  • Maximum continuous DC Current from 60A to 4015A
  • Rectifier AC voltage of up to 500VAC
  • DC bus voltage of up to 670VDC
  • RC, fuses, cooling fans and thermal switches

Diode/Thyristor Stacks Applications

The SEMISTACK CLASSIC product range is designed for fast integration of industrial rectifiers. Each power bridge has been sized to embed semiconductors with a suitable RC commutation circuit, proper AC fuses and cooling devices. The high rectifier power range has been improved using a new heatsink profile, resulting in modularity, various fan options, low maintenance and weight reductions.

Diode/Thyristor Stacks Product Range

The SEMISTACK family consists of a broad portfolio of over 200 stacks with different topologies of uncontrolled, halfcontrolled and fully controlled rectifiers. These products are available with natural or forced cooling, with or without fuses. All SEMISTACK Classics include RC protection circuitry and are optimized for fast cabinet integration.
