Abstract :In this paper, a new single phase inverter is proposed. The proposed inverter topology is obtained through modifying the well-known DC-DC buck converter to produce sine wave alternative voltage at the output. Thus, the peak value of the alternative output voltage can be provided lower than the input direct voltage value. The inverter is designed for producing alternative voltage at the output in the frequency range of 0-50 Hz. PI feedback controller is used for the control of the inverter operation. A simulation study is done for the proposed inverter and its operation in MATLAB-Simulink in order to prove its accuracy on different operation conditions. The results demonstrate that the proposed inverter can accurately produce nearly sine wave alternative voltage in various frequencies with low THD values on different operation conditions.
