Illustration Power Hardware in the Loop



Testing and emulating solutions for:

  • Grid emulation

    create high quality waveforms to emulate grids including fault conditions like HVRT, LVRT, frequency sweeps, islanding, etc

  • Dynamic sources/loads

    e.g. prosumers like family homes with PV installations and EV charger (4 Quadrant operation)

  • PV emulations

    with loads up to eight U-I curves to emulate MPPT under various conditions emulation of distributed energy resources (DER)

  • Battery storage emulation

  • Impedance Spectroscope

Go for Compiso

Advantages especially for this market



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


High-quality waveforms

Low THD together with high bandwidth allows emulation of high-quality waveforms and harmonics including sub-, inter- and super harmonics



Flexible system configurations support emulation of microgrids with up to 7 grid components simultaneously
