When we started with mobile inverters in 2009, our customers relatively soon expressed the need for supplementary functionality that goes far beyond the simple control of torque or speed of an electric motor. We then further developed the initial application-specific adaptations into a scalable and modular solution: loadable technology modules for “smart” inverters, which then become a synergetic addition to the machine control.

In electrified powertrains, we expect strongly growing importance in their complementary functions through software. The vehicle or machine control will certainly play the central role here. From over 30 years of experience in control and drive technology for production machines, we see synergetic additions for mobile applications functions in the inverter of the actuators. Here we bring in our experience of many years with most diverse production machines around clear increase in value functions to make possible.
In inverters, one needs both extremely fast and deterministic processes as well as more complex but less time-critical functions. This is often implemented with very powerful DSP (digital signal processor). We decided very early on to take a different approach: the synergetic combination of a standard microcontroller with an extremely fast FPGA (field programmable gate array). A technology in which, with over 30 years of experience, we are among the application pioneers.
Like the synergy in the combination of functions in the central machine control with those in the inverters, we also realize this in the inverter itself. Here in the duo of microcontroller and FPGA. The deterministic 2µs cycle of the FPGA is isochronous to the 500µs core cycle of the microcontroller, which offers additional superimposed cycles. And these cycles are available for our project engineers as well as for you.
Sophisticated and proven models of power semiconductors allow us to exploit the physical limits of power semiconductors technologically as well. This allows us to achieve higher realizable power from the IGBT, SiC. And this comes along with a long service life, which we can calculate and validate in real operation, even under challenging cyclical loads.
Every system is only as powerful as the tools and support. We provide support for you through our teams of service and project engineers. We have developed our own tools for programming, parameterization, analysis and diagnosis. From our many years of experience. For our teams and for you. In workshops and trainings you can get to know them directly related to your application.
