Three-Winding Coupled-Inductor-based Boost Converter with Voltage Multiplier Cell and Active Clamp Circuit for Low-Power Photovoltaic Application

This study shows a new high step up converter based on the three-winding coupled-inductor. The introduced power converter switches turn on at zero voltage switching (ZVS) condition, and all the diodes turn off at zero current switching (ZCS) condition over the entire operating scope. Therefore, the switching losses diminish, and higher switching frequency is achievable. Furthermore, it has lower EMI noises and higher efficiency due to using the soft-switching technique. The introduced power converter operates at (40 V - 80 V) at the input side. Furthermore, the output power variation is in the range of (50 W-250 W). This converter is therefore ideal for low power photovoltaic (PV) applications.
