An inverter testing system for CRAC

This paper aimed at functional requirements with CRAC (computer room air conditioning) inverter test system, and realized the test system hardware platform design, while completing the software functional design and programming algorithm. For example in Self-Made 10Kw inverter and Schneider ATV31H 2.2Kw inverter, we research on its output three-phase voltage, three-phase current for balance analysis and harmonic calculations. Practical application shows that the system can achieve efficient automated test process, and the measurement results with manual measurement are the same.
