The paper is related to the problem of generating the high quality AC voltage waveforms in distributed power generating systems with DC voltage sources like photo-voltaic farms and fuel cells. A novel approach to the synthesis of AC voltage waveforms, applying chosen analytical methods like Fourier transform, Haar wavelets transform and orthogonal vectors method, is discussed. The simulation and experimental results for the proposed complex convertor’s structures are presented in the paper.
