Abstract Role and importance of DC/DC converters have been more and more fluoresced in distributed power sys- tems applications such as photovoltaic, wind turbine, gas micro turbine and fuel cells. With regard to this charac- teristic, distributed power systems have to employ a high step-up DC/DC converter. Low voltage supply with wide range voltage drop is a distinguishing feature of these sources considering the dependency of the generated energy on weather condition. A novel high gain boost DC/ DC converter is proposed in this study. Compared with classic topologies, the boost ability of the proposed topology is strengthened. The voltage stress of the capac- itors, diodes, and power devices is reduced. The proposed converter has a switching network for the inductor which allows the use of smaller inductors. The steady-state operation of the suggested converter is analyzed thor- oughly. Finally, both the results of the simulation and laboratory prototype have verified the feasibility of the proposed topology.
