Evaluation of electromechatronical converter efficiency at modeling stage

Abstract

If the drive is designed based on the requirements for efficiency, it is necessary to check out effectiveness of control methods and design solutions at the modeling stage. For this purpose numerical model should provide measurements of the instantaneous values of efficiency. This paper offers method which allows calculations of the instantaneous efficiency of permanent magnet synchronous machine at modeling in a Simulink. The dependences of power factor and efficiency on the rotation speed is obtained.
