An Inverter Testing System For Computer Room Air Conditioning
With the rapid development of …show more content…
The research goal in this paper is the performance of inverter for CRAC and the corresponding testing system; it will be introduced in the second part. The inverter in CRAC than conventional inverter should have a higher frequency stability and harmonic suppression performance, so it is necessary to evaluate the inverter’ performance: balancing test method and harmonic test algorithm for inverter testing system will be discussed in Part III. Two Type of motor participate in the experiment. One is the AC asynchronous machine which is used often in traditional CRAC compressor, and the other is AC permanent magnet synchronous motor which is use for next generation CRAC compressor. The experimental results analysis carried out in the fourth part.
II. HARDWARE REALIZTION
The CARC inverter test system hardware structure diagram is showing in Fig.1. It is composed of portable computer and inverter testing cabinet. In the side of portable computer, the portable computer is pluged with PCI9812 acquisition card, ACL7125 relay board, PCI6208 analog output board and
