The shift to electrification presents a number of challenges for the test system: Rapid market demands are shortening development cycles to stay ahead of the competition. Another challenge is space, as existing facilities optimized for internal combustion engines have a limited footprint and must be repurposed for electrified axles. New CO2 legislation is increasing the development effort for all powertrains based on internal combustion engine technology. Finally, electrified powertrains present new challenges at higher frequencies that are not fully reproduced on the testbed. Using the same tool chain throughout the development process makes it easy to integrate the testbed.
Our answer to these challenges is AVL SPECTRA with its quantum leap technology based on SiC and Field Programmable Gate Array (FPGA) technologies. This leads to high switching frequencies of up to 48 kHz coupled with control frequencies up to 192 kHz.
High control dynamics enables simulation models to be calculated with the highest possible speed – enhancing simulation capabilities such as inertia simulation. The control dynamics is coupled with the matching dyno performance of asynchronous machines making it suitable for all typical electrified powertrains from 3,200 Nm up to over 5,000 Nm nominal torque.
SiC technology allows the AVL SPECTRA converter to be integrated in the smallest possible installation space as the footprint has been reduced compared to conventional converters.
The SPECTRA application framework allows a consistent toolchain to be used throughout your development process – use your MATLAB Simulink models for the optimization of NVH, EMC, etc., and run them directly on the SPECTRA control unit.
