Illustration Power Hardware in the Loop



Testing and emulating solutions for:

  • Grids

    Emulate grids to test charging stations against fault conditions.

  • Charging stations/battery packs

    Load individual U-I curves to emulate charge / discharge cycles.

  • Inverters

    Connect to AC and DC side simultaneously; recirculate power internally.

  • E-motors

    Run and test machines by applying required waveforms and fault conditions.

COMPISO System Unit

Case Study

RTU Riga Technical University, Institute of industrial electronics and electrical engineering

Installed System: COMPISO System Unit CSU200-1GAMP4
prepared for later extension by a second group of four amplifiers

Example 1: test of a level one onboard charger in a Volkswagen e-Up car with COMPISO unit switched to single-phase mode.
Example 2: test of a new synchronous motor design featuring windings with an asymmetric phase shift
