Device Development

Grid-forming power converters

Device development for future-proof power converter technologies

We set standards in device development for power converter technologies by combining circuit design, state-of-the-art semiconductor technology, and hardware-oriented control engineering. One of our particular strengths is our flexible hardware platform RICOSO (Rapid Inverter Control Prototyping Solution), which enables fast development cycles and precise testing of control algorithms directly on the hardware – from the initial idea to implementation.

We cover the entire development process, from topology analysis and the design of customized hardware to the integration of modern control concepts. Our focus lies on efficiency, reliability, and future-proofing.

With our research expertise and RICOSO, we offer innovative solutions that drive your projects forward and create competitive advantages.

Trust in our expertise to transform your visions into powerful systems!
