Harmonic Waveforms Analysis and Efficiency Measurement of Inverter for driving Induction Motors

유도형 모터 구동용 인버터의 고조파 파형 분석과 효율 측정

The harmonics are injurious on the operation of the motor, electric instruments etc. In this paper, it is certified the capability of the electric measuring devices at the input/output of inverter. And it is measured the harmonics of the voltage and current waveforms. Also, this paper presents the efficiency of the inverter's power conversion by measuring the fundamental and total power at the input, DC bus and output.
