a modified single-phase boost ac–ac converter using a switching cell topology

This article presents a modified direct single-phase boost ac–ac converter utilizing a switching cell (sc). the main objective is to eliminate voltage stress and minimize the size of magnetic components. the suggested non-isolated converter has a very straightforward design, which employs two inductors. the suggested design eliminates the need for dc link and provides boost capability with simple control. {r1-1} furthermore, the proposed topology reduces current levels and mitigates body-diode recovery issues, which in turn decreases switching and conduction losses and effectively minimizes the losses associated with mosfet body-diode recovery. therefore, this converter represents a practical option for many applications, such as renewable energy systems, energy storage systems, and microgrids. to improve this system's reliability and efficiency, exact and steady power regulation is essential in these domains. the operational principles of the recommended converter in various modes are analyzed comprehensively, and based on the results of the simulation in matlab/simulink. {r2-3} finally, the suggested converters' performance accuracy is confirmed by simulation analysis at 20v input, d = 0.7, 50khz switching frequency, 122v output, and 150w output power.
