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.

High Power

Test equipment at rated power up to 1.2 MW

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
