Testing facility using large capacity inverter

It is an ideal to perform a combined test of an inverter and a motor for a smooth start-up at the site. There is a method to carry out a full load test without driving a machine. It is called “Back-to-back test”. It is possible to obtain 25MW output of testing facility in our company. In this paper, it is introduced the performance evaluation of the test results such as, torque ripple analysis of the proposed system.
