Product Details:

The Danfoss power stack is a high-quality power conversion assembly and is a major building block in any larger power conversion system.  The assembly comprises of stacked and customized IGBTs (insulated-gate bipolar transistors), which gives power system suppliers the opportunity for unique performance parameters, differentiating their products from their competitors'.

For decades, Danfoss has been helping the world’s largest power system suppliers meet stringent reliability, life-time and cost targets by designing, developing, and manufacturing customized power stacks with the overall goal of optimizing system costs, to deliver competitive advantage.

We design our power stacks according to your individual mission profile – from the individual semiconductors that are used in the power modules, to the mechanical dimensions of the power stack and the control functions to be implemented. 

With the average lifespan of a power conversion system being 15–20 years, reliability, flexibility (input and output) and efficiency of power stacks are vital. Wind turbine generators and solar parks operate 24/7 and are exposed to extreme weather conditions. This calls for rugged equipment designed for heavy loads and high performance. At Danfoss you instantly benefit from years of expertise in power modules, thermal management, manufacturing and testing of power conversion equipment.

Using a modular design approach, the power stacks are customized to the specific mission profile of your application in a cost-effective manner.
