Consulting with expertise and solution competence

Specialists for power electronics

Our consulting services cover a broad spectrum to ensure that your electronic systems meet the highest performance standards. In addition to energy efficiency, size, reliability and serviceability often need to be considered and optimised. Sometimes different requirements are in conflict with each other, so that a thorough consideration of different aspects is necessary. From concept creation to product development and production, we support you with our expertise.

What is power electronics?

The term ‘power electronics’ refers to everything that has to do with controlling, converting or switching electrical energy with electronic components. This starts at just a few 100 mA and a few volts, but extends up to 100 kV and several 1000 A.

Our experienced engineers analyse your requirements in detail and develop customised solutions that are precisely tailored to your needs. We support you in selecting the right components, integrating new technologies and optimising existing systems. The technical development and performance of power semiconductors is also progressing steadily. Applications that could previously only be realised with thyristors are now being solved with IGBTs. In the medium power range, IGBTs are being replaced by SIC or GAN semiconductors. Together with you, we look for potential savings through the intelligent use of power electronics. After all, our advice should not only improve your application, but also make it as cost-effective as possible.

Whether it's the development of power modules, the optimisation of power supply systems or the implementation of power electronics in medical technology - we are your reliable partner for expert consulting services.

I look forward to discussing your individual technical requirements with you and demonstrating our expertise as a solution provider and problem solver.

Dr. Ing. Henrik Siebel
Managing Director

We offer you comprehensive expertise and customized solutions for your individual requirements.
