| Abstract: | The topology, characteristics and working principles of there-level converter, are expounded.Several arrangment and principles are illustrated. Mathematical analysis is made to its harmonic characteristics.The harmonic contents and distribution of there-level converter are deduced by double Fourier Series. Finallygiven is the simulation waveform. The results verify the correctness of the theoretical analysis. |
