COMPISO Power Hardware in the Loop

The COMPISO System Unit is a galvanically isolated bidirectional emulation and test system with either four or six independent four-quadrant power amplifiers. It can operate in one of several predefined AC and DC operation modes as well as in a wide range of user-defined HIL-based modes. Featuring current-control, voltage-control and mixed-mode capability combined with 5kHz large-signal bandwidth and 15kHz small-signal bandwidth, the COMPISO System Unit is the most versatile high-power PHIL test and emulation platform currently on the market. The COMPISO System Unit system can be controlled by external HIL systems via a fast fiber-optic or analog interface.
