Abstract: The rate of utilization of renewable energy sources is increasing nowadays. Since renewable energy source depends on environmental conditions, its output will vary according to the variations of weather condition. In order to get a steady output at the load side, an inverter is required that shows the property of bucking and boosting the input voltage by eliminating the input disturbances. This paper proposes one cycle controlled buckboost inverter. It has the ability to buck and boost the input voltage by rejecting its disturbances. The detailed Matlab/Simulink model has been used to verify the performance of the system. Three test conditions are used to substantiate the performance of the proposed inverter such as the ability to buck and boost the input voltage, rejects the disturbances in the input side. Test results validate that the proposed inverter used for the applications where input varies.
