DS5202 FPGA Base Board

For high-resolution signal preprocessing

  • FPGA application-specific-programmable on a per project basis
  • Piggy-back module with application-specific I/O drivers
  • S-functions programmed on per project basis

Application Areas
The board has been designed for hardware-in-the-loop simulations that require very fast, high-resolution signal preprocessing, for example:

  • High-precision digital capturing of 3-phase PWM signals
  • Simulation of engine speed/position sensors for electric motors
  • Fast current/voltage measurements, connection of diverse position encoders and control of AC motors
  • Electric motor simulation
  • Connection of dSPACE real-time systems to EtherCAT networks as slaves

Key Benefits
The components of the FPGA Base board are always tailored to specific applications, according to customers‘ specification, and can be adapted to other projects. Algorithms for real-time applications with high sampling rates can be shifted to the FPGA (field programmable gate array). The time resolution of the signals depends on how the FPGA is programmed. The reference frequency for the control loop is set in the digital frequency synthesizer (DFS). Even with complex FPGA algorithms, the typical working range is 40 - 80 MHz. The piggy-back module allows flexible integration of I/O drivers and special combinations of analog/digital inputs/outputs and bus drivers.
