EMTP를 이용한 인버터 구동 고압 유도전동기의 스위칭 써지 특성 분석
The Analysis on the Switching Surge of High-voltage Induction Motor fed by Inverter Using EMTP

초록
The PWM inverter drive my cause motor terminals voltage surge and oscillation(ringing), which impose severe electric stresses on inter-turn insulation of motor windings. This paper describes the technique used to simulate the problems associated with the use of PWM ASD's(Adjustable Speed Drive) to drive induction motor. The characteristic of switching surge was analyzed by EMTP(Electromagnetic transient program) model. The effects of switching surge by surge impedance, rise-time and cable lengths are also discussed.
