This study discusses the derivation of the continuous input current high‐voltage gain DC–DC converters. These converters are very suitable for renewable energy sources such as photovoltaic power systems since high‐output‐voltage gain is required for grid connection and continuous input current is necessary for better input current regulation. In these structures, coupled inductors are used along with voltage multiplier cells to improve the voltage gain. Passive clamps are also applied to recover the remained energy in the coupled inductors and improve the efficiency. Regenerative snubbers mitigate the voltage stress on the main switch. Various advantages of the studied converters make them suitable for renewable energy sources with low‐output DC voltage. A thorough comparison section is provided to assess the performance of the presented converters. For simplicity, a converter is selected and analysed in details and design guidelines are presented. The experimental setup is implemented in the laboratory to prove the proper operation of the converter.
