چکیده	High step-down non-isolated DC-DC converter with coupled inductors is proposed. The converter is used a simple lossless clamping circuit. Moreover, it produces the current ripple cancelation at the output due to series connection between the coupled inductors and the output. Automatic current sharing is done in the proposed converter even if the switches have different duty cycles. The proposed converter has lower voltage stress in comparison with traditional Buck converter and also different topologies of Buck converters with the coupled inductors. Besides, the current stress on semiconductor devices is reduced due to the interleaved structure. Finally, the converter has lower number of components in comparison with the similar structures. The mentioned advantages candidates the proposed converter to apply in photovoltaic system. A 200 W laboratory prototype converter is considered and constructed. The experimental results presented confirm the aforementioned features and theoretical analysis.
