摘要：

This study introduces an innovative high step-up (HSU) converter designed for solar photovoltaic systems equipped with a maximum power point (MPP) tracker. This converter efficiently increases the output voltage while maintaining low voltage stress on its components, thanks to a novel combination of primary boost cells, switched capacitors, and voltage multiplier cells. A clamping circuit minimizes leakage energy, enhancing overall efficiency. Testing of a prototype confirmed its effective MPP tracking and high efficiency, with a conversion rate of 20 V-40 V to 380 V at 150 W and efficiencies between 90 % and 96 %.
