A New High Voltage Gain SEPIC-Based DC-DC Converter without Coupled Inductor for Photovoltaic Systems

A new single-ended primary-inductor converter (SEPIC)-based DC-DC converter suitable for photovoltaic (PV) systems is introduced. The proposed converter has the advantage of continuous input current which reduces the input voltage ripple across the PV panels. Furthermore, it can provide a higher-voltage gain at smaller duty cycles when compared with counterpart SEPIC-based topologies which feature...
