Furthermore, it is possible to emulate many important aspects for fault simulation, such as leakage currents, zero currents, or current-limited short circuits. Because the currents can be emulated precisely, it is possible to display ripple currents as well as harmonic frequencies, which allows for testing the latest control concepts. By frontloading the conventional dynamometer testing to emulators, the high-voltage electronic loads integrate seamlessly into hardware-in-the-loop (HIL) validation.

In addition, high-frequency rotating fields and all operation points of an electric motor can be emulated, both in motor and generator operation.

Thanks to their high dynamics and low self-inductance, the high-voltage loads can emulate variable motor inductances. TECHNICAL SPECIFICATIONS: DSPACE Description: DSpace is an out-of-the-box open source software package for creating repositories focused on delivering digital content to end users and providing a full set of tools for managing and preserving content within the application. An open (Simulink/Xilinx) library from dSPACE provides the required simulation models, from FPGA models for motors and incremental encoders to the dSPACE Automotive Simulation Models (ASMs) for batteries and complete powertrains. The energy flow in the system circulates without complex grid feedback, leading to additional efficiency and minimum load on the mains supply. Using the same hardware for the emulation of loads, such as electric motors, and sources, such as batteries and the AC grid, makes the systems cost-effective and easy to maintain. The compact units can be flexibly used with regard to currents, number of phases, as well as the type of voltage source to be emulated. The new high-voltage load hardware features a compact design and modular setup. These power hardware-in-the-loop (PHIL) capabilities make dSPACE a unique provider of single-source, ready-to-use simulation solutions for the complete range of electric vehicle drives. The hardware-in-the-loop (HIL) systems from dSPACE now allow for the highly dynamic emulation of electric motor and battery components with voltages up to 800 V, which means that all drive components of hybrid and fully electric drives can be represented with a real energy flow. DSPACE recently complemented its product portfolio for the simulation of electric drives.
