Testing traction inverters, including the controller and power electronics, at full power can be a challenge. Real components are not yet available or the conventional test benches simply don’t offer enough flexibility to test the controller robustness. This is where Power HIL systems come into play.

Power Hardware-in-the-Loop (Power HIL) simulators can provide testing capabilities for motor inverters during development and validation of electric motor drive systems. The Power HIL provides the emulation of real-world electrical grid conditions and motor loads to assess the performance and reliability of the motor inverter. Simulating various operating scenarios, including voltage sags, surges, and transient events, Power HIL testing allows engineers to thoroughly evaluate an inverter's response, control algorithms, and fault tolerance.

Join this session about the Power HIL systems that dSPACE offers—tailor-made for HIL simulation at the power level. dSPACE systems offer the flexibility to test the inverter without the real motor, allowing for configuration changes, without hardware changes, enabling true-of-life simulation without mechanical limitation. dSPACE Power HIL Systems combine the flexibility of established HIL systems with the full power found on dynamometers or in real-world prototypes.
