This digest proposes a new DC–DC/AC flyback-based power converter with the least number of components featuring a dynamic voltage conversion ratio. This converter serves as a power electronics interface, adaptable for employment in DC, or AC grids or loads using the similar terminals. A distinctive characteristic of this converter lies in its employment of identical components to achieve both DC–AC and DC–DC power conversions, leading to an optimized and effective design with minimal components. As a result, this converter exhibits considerable promise for contemporary applications, particularly in the context of renewable energy sources. For example, it enables the seamless integration of solar systems into either DC or AC grids/loads by serving as an intermediary interface between the energy source and the grid or load. Generally, the proposed converter aims to enable future hybrid DC and AC microgrids. To substantiate the efficacy of the proposed power converter, the paper offers a succinct mathematical analysis, brief comparisons, and simulation results, performed with MATLAB/Simulink.
