Abstract: No doubt that, power electronics play an important role in the modern industry and power system networks. This paper presents the performance analysis of a multi-source, single-output, buck-boost dc-ac converter suitable for use in different applications such as feeding ac loads from photovoltaic systems. In this paper, the performance of the proposed converter is studied, through power simulation program (PSIM), under different modes of operation during feeding active power to a distribution network. The most important features of the proposed converter are the possibility to control voltage, frequency, voltage and frequency together, and the low value of the total harmonic distortion (THD) in the voltage and current waveforms.
