Overview

With our comprehensive portfolio of stack assemblies, we offer our support as leading manufacturer of power semiconductors, and we develop a huge number of customer-specific stack assemblies yearly. Over 20 cooling block concepts out of three product lines enable the design of power electronic assemblies for voltages up to 20 kV. From more than 25,000 variants, we provide the best fitting power stack specifically for your requirements.

About

Building blocks

The design lines by basic building blocks support the requirements from semiconductors, applications, and markets:

Compact Block: Designed for thyristor and diode modules in pressure contact or solder bond technology and defined by a potential-free common compact heatsink.

Frame Blocks: Designed for thyristor and diode discs and defined by high-efficient, two-sided air cooling with perfect electrical conductivity in an insulating plastic frame.

Tower Blocks: Designed for thyristor and diode discs up to 8 kV and defined by the highest insulation capability, highest current capability, and for series connection of discs. It is recommended for pulsed power applications and follows a tower design.

Power Fit: Accessories for blocks and stacks are a support for hoses for liquid cooling, water collectors, and mechanical setup in the cabinet. In addition, the accessories for stacks support liquid cooling cool back systems, air stream monitoring, and controllers.

Key benefits and applications

Power stacks incorporate important key benefits such as risk reduction with approved heatsink and mounting concepts for all bipolar semiconductors, acceleration of development projects and cost reduction with one-stop service, achievement of a shorter time-to-market with your products and usage of our excellent design-in support.

Power stacks can be used in a wide range of applications such as motor control and drives, UPS, and power converters and inverters for wind turbines.

4 steps to your individual power stack

We support your requests for flexible building blocks:

  1. Find a module or disc which supports your application needs
  2. Choose one of the building blocks for basic circuits
  3. Define the stack from blocks according to the application needs
  4. Add accessories according to applications needs
