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.

Superior Control
The ultra-fast 1MHz control cycle reduces dead times and allows execution of highly dynamic test cases. In addition, it enables inertia simulation which widens the field of application for your testbed.
High Switching Frequency Without Derating
The fully water-cooled SiC power electronics are capable of high switching frequencies without the drawback of current derating.
