Low-Voltage Testing

Low-voltage emulation of e-mobility components

Using multiple low-voltage electronic loads in parallel makes it possible to reach up to several kilowatts of power. Typical test application areas include electric power steering (EPS) systems, starter and generator systems, two-wheelers, secondary drives, and mild hybrid drives.

  • Model-based current emulation with highest dynamics for emulation of the current ripple
  • Parallel connection for high-power applications such as mild hybrids
  • Compact design that fits into standard dSPACE HIL simulators

Typical power HIL system based on low-voltage electronic loads for testing mild hybrid drives.

The electronic loads can either be completely integrated into a standard HIL cabinet or combined with several external components, such as high-current failure insertion units (FIU) or climate chambers.

Unique Features

  • Outstanding and very realistic current emulation
  • Identical modeling environment for tests on the signal level and the power level
  • Specifically tailored for hardware-in-the-loop (HIL) simulation at the power level
  • Current-based emulation for simulating variable motor inductances without the necessity for switching or exchanging any hardware components
  • Support of discontinuous conduction for the emulation of sensorless brushless DC (BLDC) motors
  • Safe test conditions due to safety mechanisms for power electronics
