Paper Title - Analysis Of Efficient Solar Power Optimizer For DC Distribution System
This paper presents a high step-up gain Solar Power Optimizer (SPO) to harvests maximum energy from a
photovoltaic (PV) panel and feed this energy to a DC micro -grid. The arrangement consists of coupled inductor and
switched capacitor to increase voltage gain. The leakage inductance energy of the coupled inductor can be recycled to reduce
voltage stress and power losses across the power device. Low voltages rating and low-conduction resistance power switch
improves system efficiency by employing the incremental conductance algorithm method for the maximum power point
tracking (MPPT). Because of its high tracking accuracy, the method is used in the energy harvest from PV systems. The
planned SPO that have an input voltage range of 20 to 40 V and a maximum PV output power of 400 V/300 W are
considered. The highest PV power conversion efficiency is 97%. The maximum MPPT accuracy is 99%. The above
efficiency obtained is verified by using MATLAB simulink.
Keywords- High Step-up Voltage Gain, Maximum Power Point Tracking (MPPT), Solar Power Optimizer (SPO),
