Utilizing high step up dc-dc boost converter with interleaved fly back boost converter topology and Maximum Power Point Tracking Method (MPPT) algorithm for optimal harvesting of solar radiation

PV generation is one of the fast-growing renewable power generation system; it helps to meet the ever-growing power demand. Among the various PV generation techniques available, the micro inverter system which finds its application in roof top systems is rated as one of the best option for maximum energy harvest from each solar panel. Poor harvesting of solar energy due to shading has been identified as a major setback for PV-based renewable power generation systems. Hence, this paper presents a simulation of a 46kVA micro-inverter utilizing a high step-up dc-dc boost converter with Interleaved Fly back boost converter topology and a Maximum power point tracking method (MPPT) algorithm for optimal harvesting of solar radiation. Solar panels, DC-DC converter, DC-AC inverter, and LC filter make up the Micro Inverter architecture. The solar cell provides electricity to a DC-DC converter, which increases the input DC voltage to the inverter's desired rated input voltage. A pi filter is used between the converter and inverter circuits to eliminate ripple.
