The medium frequency (400 Hz) power systems supply energy to the critical system and loads in aerospace, airplane and vessel, where space and weight are at a premium. The converters are demanded to obtain 400Hz power from civil 50/60Hz power systems. There are mainly two types of converters: solid state frequency converter (SSFC) and rotary frequency converter (RFC). There are various evaluations about the converters in different papers. The eight characteristics of two converters have been investigated in detail. The comparison between solid state frequency converters and rotary frequency converters is analyzed, and the applicable requirements and conclusions are presented in the final.

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.

The I/O performance test system of inverter is designed. ADlink PCI board and signal regulating panel are core of hardware platform. The software uses the mixed programs, that is, the graph control of Labview and Microsoft Visual C++. Based on the eight analog inputs, two analog outputs, three digital inputs and four digital outputs provided with specific application, we fulfill the following assignments: the dynamic monitoring of three-phase input current/voltage, DC-bus voltage and actual rotation speed, curve drawing and data storage. The computer could give the enable signal and analog speed of inverter, besides the failures are read and displayed. Finally the harmonic analysis and the balance analysis of three-phase current/voltage are realized.
