In this paper, a stand-alone photovoltaic (PV) system based on a Double Ended Forward Converter (DEFC) is presented. The proposed converter is specified for 48 V, 100 W applications as most of the equipment used in telecommunication and aircraft fall in this range. The literature has limited potential application of DEFC in PV systems. The research work deals with an in-depth study of DEFC and proposes an improved DEFC for PV applications with battery backup. Besides, a bi-directional dc-dc converter for the battery is integrated to track the Maximum Power Point (MPP) of the PV generator. The converter is examined under variable irradiance and load conditions, and the analytical analysis of boundary conditions are implemented. The converter's architecture also ensures built-in I-V curve tracing for the identification of MPP of PV generator. It offers low voltage stresses across switches and avoids sinking power supply and core resetting circuits. The topology's behavior is analyzed based on MPP achievement and maintaining output under different conditions of battery backup availability, environmental, and load conditions. The PV system architecture is designed and analyzed theoretically and verified with simulations on the PSIM software.

“…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.…”

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.
