Do you want to test inverters, including the controller and power electronics, extensively at full power? But real components are not yet available, and conventional test benches simply don’t offer enough flexibility to test the controller robustness? This is where our power HIL systems come into play: Tailor-made for hardware-in-the-loop (HIL) simulation at the power level, they combine the flexibility of established HIL systems with the full power found on dynamometers or in real-world prototypes.
Thanks to our established current-based emulation, our power HIL systems can be used flexibly for virtually any kind of component, e.g., motors, batteries, photovoltaic panels, or power grids.

Our Solution Highlights
- Turn-key power HIL systems as well as modular hardware for different applications and specialized topologies
- Testing electric motor controllers, including power electronics with emulated motors and real currents
- Easy configuration of different motor types using plant models, eliminating the need for hardware changes
- Early testing by frontloading the tests to an early development phase, e.g., inverter tests without real components
- Easy adjusting of system power to individual test requirements, e.g., by adding more emulation cabinets to existing test systems, thanks to the modular approach and the generic power cabinet design
- Easy installation thanks to the lighter weight, smaller dimensions, and fewer grid requirements compared to mechanical test benches
- Reduced risk for the user and the equipment thanks to virtualization (no moving parts)
With our power HIL (PHIL) test systems, we offer ready-to-use solutions for testing inverters, including the controller and power electronics, at full power. Using real voltages and currents, our systems enable you to complete exceptionally rigorous tests of the power electronics.
Our test systems behave like a digital twin of the real system – with one decisive advantage: They can be configured with just a few clicks, which significantly reduces setup times. For this purpose, dSPACE offers various open Simulink®/Xilinx® models for processor-based and FPGA-based simulation. The XSG Electric Components Library from dSPACE includes motor and encoder models for FPGA-based simulation. A battery model is included in the dSPACE Automotive Simulation Models (ASM) tool suite. Using the dSPACE Electrical Power Systems Simulation (EPSS) Package, you can also integrate complex grid models. Finally, combining these models even allows for the simulation of complete electric powertrains or complex grid applications.
