Abstract
The effects of interharmonics, which are defined as non-integer multiples of fundamental or switching frequencies in power utility connected VSI/CSI systems, are different from integer harmonics. A new approach is proposed in this paper based on the "non-linear modulator" concept to describe the generation of harmonics and interharmonics in generalized power converters. Subsequently, the analytical model is concluded and analyzed for conventional d-q rotating reference frame controller in VSI converter. Moreover, effects of feedback control strategy and additional compensation blocks are considered. Analysis validation is also confirmed by simulation results.
