N2 - This paper proposed a novel high step-up solar power optimizer (SPO), which efficiently harvests maximum energy from photovoltaic (PV) panel then output to DC micro-grid. It combines coupled inductor and switched-capacitor technologies to achieve high step-up voltage gain. The leakage inductance energy of the coupled inductor can be recycled to reduce the voltage stress and power losses. Therefore, low voltage rating and low conduction resistance switch can be selected to improve system efficiency. Laboratory prototypes of the proposed SPO with an input voltage arrange of 20 ∼ 40 V and the maximum output 400 V / 300 W is implemented to verify the performance and MPPT accuracy when connected to DC micro-grid simulator.
