“…These converters can provide high voltage levels with high efficiency at output side suitable for renewable energy applications [4]. Many topologies have been introduced for this purpose [5][6][7][8][9][10][11][12][13][14][15][16][17] such as 1) using coupled inductor, 2) using voltage multiplier, 3) using switched capacitor, 4) using cascaded techniques, and 5) switched inductor. Coupled inductor chooses to use in high gain by increasing inductor turns ratio.…”

“…However, the number of components is large, and the output diode voltage stress is high. Reference [14] described converter uses switched capacitor and a coupled inductor, where the voltage boosted by increasing the turns ratio of the coupled inductor and switched capacitor stage. This converter suffers from high transient current that has degrading effect on both efficiency and power density.…”

In this paper a single switch non-isolated high voltage gain DC/DC converter based on the conventional converter and a switched inductor is introduced. The operation and analysis of the converter in the continuous conduction mode (CCM) and discontinuous conduction mode (DCM), and voltage gain equation derivation are also presented. Also, design of the converter parameters (inductors and capacitor) is given. The proposed converter achieves continuous input current that suitable for PV applications. Also, it is characterized by simplicity of installation and eases of operation which decreases the power losses and gives high overall efficiency. A prototype is made in laboratory to validate the effectiveness of the proposed converter. The proposed converter operation is tested experimentally with static and dynamic load. Also, the performance of the proposed converter is examined with an open loop and closed loop controllers. In addition, a comparison between the proposed converter and other recent converters is also introduced to confirm the merits of this converter.
