Abstract

A new direct harmonic analysis approach for AC/DC/AC conversion system is presented and discussed. It uses the characteristic of the vectors and their sequence characteristic to obtain the voltage and current transfer rules of the converters in conversion system, and then get the direct harmonic analysis method of the whole AC/DC/AC. The method can deduce the expression of AC harmonic current from AC voltage, and does not require iteration between AC and DC side. The results obtained by direct harmonic method were verified using time domain simulations.
