The Analysis for the Characteristics of Switching Surge of Adjustable Speed Drive by Inverter

인버터에 의한 가변속 구동장치의 스위칭 써지 특성 분석

By development of power electronics technology, the increasing of inverter's switching frequency lead to the development of speed control technology of induction motor. But the surge voltage including harmonic component in output waveform can cause the motor to generate power losses, torque ripple, acoustic noise and oscillation. This paper is analyzed the characteristics for switching surge of adjustable speed drive and is presented the problem by inverter.
