The structure

Standardized modules, flexibly configured

A standardized hardware platform and flexible configuration options: This allows solutions to be tailored specifically to the application without having to redevelop each system from scratch.

Base

knestronX Rack and ITS Power Modules

The ITS Power Modules in the knestronX rack serve as the common hardware across all configurations, with power outputs of up to >100 kW per module.

Configuration

Topologies and Options

Depending on the topology, the same modules can be used to create step-down converters, bidirectional DC/DC converters, H-bridges, or inverters. Additional options include balancers, galvanic isolation, and cooling.

Application

Your solution

Freely configurable systems for your application or preconfigured products for typical tasks such as battery simulation and battery testing.

Topologies

The right topology for your application

Depending on the application, power electronics require different degrees of flexibility: bidirectional energy flow, galvanic isolation, and voltage step-up and step-down. The knestronX Rack combines standardized modules into various topologies to meet these needs, and we’ll work with you to select the right one.
