Popis: Differential boost inverters (DBI) formed by differentially connected two dc-dc converters to produce singlephase AC voltage. DC-DC converters in DBIs are developing the voltage higher than peak of the output voltage waveform and experiencing higher voltage and current stresses. Thereby causing more power loss and lower efficiency issues. In this paper, new differential buck-boost inverter (DBBI) is presented to reduce the voltage stress of semiconductor devices and inductor currents. The detailed operation of the proposed inverter is explained. Also, simulation results and comprehensive comparative analysis are presented.
