Illustration Power Hardware in the Loop


Renewable Energy

Testing and emulating solutions for:

  • Grids

    Emulate grids to evaluate inverters against fault conditions.

  • PV inverters

    Shorten your R&D cycle and save costs by testing and emulating

  • Wind Inverters

    Step up output voltages to test wind inverters up to several kV.

  • Impedance Spectroscopy

    Investigate your system for harmful resonances and learn to avoid them in the field

Go for Compiso

Advantages especially for this market



Use a single system to test various types of equipment



Reduce energy consumption when testing input and output stages of your hardware under test simultaneously by recirculating power


Ultra-high bandwidth

Allows to modulate small signals on top of waveforms to investigate resonance behaviour.

Multi-Purpose Turnkey

Power Amplifiers

We provide the most versatile high-power PHIL test and emulation platforms currently on the market. Accessories like Digital Oscilloscope, Simulation Models and CABINET I/O Box can be found here.
