Abstract
A new method that can be used in the calculation of characteristic harmonic components generated by a converter system is described. This is based on modulation theory and an AC side equivalent circuit for a converter is deri ved. The effects of the commutation overlaps and impedance are correctly re presented providing that the overlap angles are known. Using this method, t he entire harmonic calculation can be performed at the AC side of the conve rter, thus substantially simplifying the harmonic analysis process. This me thod is particularly useful when information on the DC link is not needed. A new understanding into the mechanism of harmonic generation in converter systems is also provided.
