The DS5381 Low-Voltage Electronic Load Unit from dSPACE emulates motor and generator currents for hardware-in-the-loop (HIL) simulation. With up to 60 V, the module is also ideal for use with higher onboard vehicle voltages of 48 V.
Perfectly suited for three-phase motor applications
100 A per module, higher currents through parallel operation
Operates with FPGA-based motor simulation
Only one load unit is required to emulate a battery-powered three-phase electric motor. Typical test application areas include electric power steering (EPS) systems, starter and generator systems, and mild hybrid drives.
The DS5381 Low-Voltage Electronic Load Unit uses the same supply voltage as the device under test, e.g., the ECU. This means that the effective power that circulates between the ECU and the DS5381 Low-Voltage Electronic Load Unit can be much higher than the power fed in by the DC supply unit. This energy recuperation significantly increases the energy efficiency of the overall system. To boost the overall system power, multiple loads can be operated in parallel to achieve higher electric currents.
