Abstract

Because most LIM is driven by inverter, input voltage is involved with the time harmonics. Therefore the equiLlQ/ent circuit for an inverter-fed LIM has to be modified to represent every harmonics present in supply voltage. This paper analyzes the characteristics and loss of LIM to construct the equivalent circuit for each time harmonics through the static test and theoretical analysis. To make an analysis of nonsinusoidal supply waveforms, it is developed the simulation program to calculate the RMS, peak value and THD for any waveforms expressing Fourier series.
