Abstract：Inter-harmonics in frequency converters has gained more and more attention. This paper takes common current source inverter (CSI) as an example, and adopts the modulation theory and Fourier analysis of the switch function to analyze the equivalent impedance characteristic of the CSI, and further deduce the mechanism of CSI producing harmonics in the source side, from which the inter-harmonic model of frequency converter for engineering application is established. Relying on the practical variable frequency starting system of a pumped storage power station and combining with computer simulation, the comparing results verify the reliability of the model.
