Technology modules

An open mobile double inverter by ARADEX with visible hardware

Added value through inverters with technology modules

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.

Synergy: Control & Inverter

Function modules directly on the actuator inverter complement the overall processes in the machine control system.

Realtime & Deterministic

All modules are executed within the 0.5 ms cycle and in a defined order.

Standard & Customized

You can combine modules from ARADEX with your own or specially developed ones.

Experience from many production machines now available for use in mobile machines.

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.

Powerful Duo: Microcontroller & FPGA

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.

Functional duo: Firmware & Software

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.

Enable more power

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.
