AFCI Software Integration

SMA

  • Signal processing to protect solar DC strings
  • MOAID performance optimization
  • TMS320F28379D, Soprano, uCos, Matlab Simulink
  • Embedded coder runtime verifications
  • Multicore optimizations
  • AFCI implementation. To get a highspeed-ADC channel – I had to revise the ADC channel allocation and auto-muxing. This also influenced analog compare circuitry in the realtime partition of the device. I had to free up memory for buffering and add co-processor routines to store this data. As this product underlies function safety concerns – making this changes required a lot of re-certification and testing effort

NA-Protection, Anti-Islanding recognition, AC Converter

Trumpf-Hüttinger

  • Hüttinger was developing power-inverters to test and operate redox-flow batteries as backup devices
  • Part of the needed integrated protection towards mains is an anti-islanding detection
  • This detection should be capable to shut of the inverter if mains grid fails
  • The presence of mains should even cover situations which almost no current drawn from mains
  • I implemented a very sensible sliding fixed-point DFT to measure even minimal phaseshifts. This was combined with ramping injection of reactive current
  • After implementation and simulation – the converter was tested against mains simulators and finally approved @Buero Veritas, Bad Wörishofen
  • TI, Delfino, Matlab, TMS320F28377D, TMS320C28346
