Power stacks

Power stacks

Proton-Electrotex can design and assemble power stacks customized per individual inquiry.

According to needs and tasks of each customer Proton-Electrotex can supply the following types of power stacks:

High-voltage impulse thyristor switches

Features of the power stack:

  • Current amplitude up to 250 kA
  • Surge current growth rate up to 10 kA/µs
  • Voltage up to 28 kV

This type of stacks is often used in pulse discharge devices for high-power lasers, systems and magnetizers.

Three-phase AC switches

Features of the power stack:

  • Nominal voltage 0.4 – 6 – 10 kV
  • Nominal engine power – up to 1 MW
  • Nominal voltage0.4 – 6 – 10 kV
  • Nominal current – up to 4 kA
  • Nominal voltage0.4 – 6 – 10 kV
  • Nominal current – up to 10 kA

This type of stacks is often used in soft starters for asynchronous electric drives, static AC switches for UPS and emergency reserve power switches.

Power rectifier blocks

Features of the power stack:

  • Nominal voltage 0.4 – 6 – 10 kV
  • Rectifying current – up to 2500 A

This type of power assemblies is used in high-spec power sources, frequency converters, traction drives, rectifiers for galvanizers, and battery rechargers.

Inverter cells

Features:

  • Nominal voltage 0.4 – 0.69 kV
  • Output power up to до 300 kW
  • Liquid or forced air cooling

This type of stacks is used in frequency converters, traction drives, inverters for renewable power industry.

All power stacks except semiconductor switches can be equipped with snubber circuits, resistive dividers, drivers, current, voltage and temperature sensors.

Benefits of using power stacks made by Proton-Electrotex

  • Saving the time to design the converters
  • Reduction of costs related to design and production of the power stacks
  • Individual solution for every customer
  • Technical solutions are selected on the basis of specific application of power semiconductors
  • Increased reliability of the converter due to using only verified solutions
