누설 전류를 고려한 인버터 구동 유도 전동기 모델 시뮬레이션

Abstract

It is required to analyze the characteristics of inverter-fed induction motor according to the increase of inverter uses. However the previous simulation researches usually uses simplified induction motor model and fixed power source because the difficulties of their modeling and analysis. In this study, high frequency induction motor is simulated and the induction motor model considering high frequency characteristics is developed and it is combined with inverter model. With these, from the sinusoidal commercial frequency to PWM high frequency, induction motor characteristics can be simulated and analyzed.
