AVL is the world's largest independent company for development of powertrains (combustion engines, hybrid systems, electric drive) as well as simulation and test systems for passenger cars, trucks and marine engines.

We offer a master thesis:

Firmware Development Concepts for a commercial Fuel Cell and Battery Monitoring Equipment


  • Optimized Utilization of the current THDA-Hardware:The internal sampling rate is currently 8.1 kHz. The used sigma delta ADC are capable to be operated at higher bandwidth. The limiting factor is the micro controller (TMS320C28346). It needs to be figured out what the max bandwidth is, what the micro controller can handle or what effort is needed to enlarge the bandwidth above 50 kHz.
  • Implementation of a Data Exchange Inteface:To transfer the high frequency data a data communication port needs to be added (e.g., Ethernet or USB).
  • Evaluation of Time-Domain based Algorithms Inside the Existing Hardware:THDA is based on the estimation of amplitudes of harmonic signals at the output (e.g., Voltage) that are generated by harmonic input excitations (e.g., AC current). The current estimation algorithm inside the firmware is based on the fast Fourier transformation (FFT) in the frequency domain. As an alternative, the on-line estimation of harmonic amplitudes can be done in the time domain by suitable filter algorithms. In a previous master thesis innovative algorithms have been investigated. The algorithms are available in form of Matlab functions. It should be clarified, if it is advantageous to implement one of these new amplitude estimation methods inside the firmware.
