Abstract


Multi-level converters have tremendous applications in the power industry and specially cascaded H-bridge (CHB) converters have a vital role in high power applications. They present a new set of features that are well suited for real and reactive power compensation. The distinctive feature of the multilevel inverters is to provide high switching frequencies with low switching losses. In this paper, power balance analysis of single phase cascaded H bridge converter is presented. Power delivering from source to load or load to grid is analyzed by required ac output voltage and from de link voltages. Detailed power balance analysis of this converter has been carried out using MATLAB/SIMULINK and simulation results are shown.

Keywords
