介绍了交流变频技术在涡轮增压器试验台上的应用及原理,采用变频技术后,不但使增压器转速控制更准确、简捷,而且提高了压气机空气流量测试精度。 The application and principle of AC frequency conversion technology on the turbocharger test bench are introduced. After the frequency conversion technology is adopted, the speed control of the supercharger is not only more accurate and simple, but also the accuracy of the air flow test of the compressor is improved.
