Aerospace Hardware in the Loop Simulation for Electrical Power Systems
As the aerospace industry rapidly advances toward electrification and More Electric Aircraft (MEA) architectures, hardware in the loop simulation has become essential for validating complex electrical power systems safely and efficiently. Impedyme, a pioneer in combined HIL and Power HIL (PHIL) solutions, leverages cutting-edge FPGA-based platforms, integrated motor emulators, and high-fidelity inverter testing capabilities to provide aerospace engineers with realistic, real-time simulation environments. These state-of-the-art solutions enable early detection of design flaws, comprehensive testing of power electronics and propulsion systems, and accelerated development cycles—ensuring safer, more reliable aircraft electrical systems before physical prototypes or flight tests are undertaken.
Combined HIL and power Solutions for Aerospace Validation
Hardware in the loop simulation is a critical methodology for testing aircraft electrical power systems under realistic, repeatable conditions. Impedyme leads the field as a pioneer in combined HIL and Power HIL (CHP) platforms specially designed for aerospace applications.
Impedyme’s CHP system merges high-fidelity real‑time FPGA‑based HIL with real power‑level emulation (PHIL), enabling:
- Full-scale inverter testing and motor emulator scenarios using real voltage/current interaction.
- Simulation of high-frequency PWM signals with sub‑microsecond resolution, reducing emulation error under 1 %
- Accurate reproduction of nonlinear motor dynamics—magnetic saturation, cogging, hysteresis—via FEA-informed lookup tables on FPGA hardware
This unified Power HIL architecture empowers aerospace engineers to emulate aircraft power distribution, propulsion drives, and More Electric Aircraft (MEA) subsystems in a controlled lab setting before physical prototypes or flight tests.
Why Impedyme is the Leading Choice
1.State‑of‑the‑Art FPGA‑Based Hardware‑In‑the‑Loop
Traditional processor-based HIL systems are limited to around 20–50 kHz. Impedyme’s FPGA real-time simulation achieves time-steps faster than 1 µs, yielding far higher accuracy in hardware in the loop simulation, especially important for high-frequency PWM and inverter validation.
2. Integrated Motor Emulator & Inverter Testing
Impedyme’s motor emulator integrates with CHP for seamless transition from signal-level testing to full power-level testing, enabling inverters and propulsion units to be evaluated under realistic torque, load, and communication protocol scenarios—even without physical motors.
3. Scalable Thermal & Power Architecture
High-voltage PHIL platforms like the CHP 150 or PHIL 300 offer modular architecture and advanced liquid-cooled thermal management to safely emulate megawatt-class systems, ideal for aircraft power electronics and propulsion subsystems.
4. Accelerated MEA System Development
For modern More Electric Aircraft, where hydraulic and pneumatic systems are replaced with electrical equivalents, Impedyme’s CHP enables rapid iteration under multiple fault and operational scenarios—identifying power quality issues, EMI, or thermal risks before real-world testing.
