Photovoltaic (PV) power generation requires a bigger area per unit capacity than traditional power plants since it employs a limitless and clean energy source. As a result, installing floating PV systems (FPVs) on open sea surfaces is becoming more common in countries with tiny landmasses, such as South Korea, Japan, and Vietnam. For use in applications involving PV systems, this paper suggests a design for a high-gain LUO converter. This proposed system consists of a LUO converter for a PV system. A converter’s output voltage can be increased while staying constant throughout the system by using the proposed converter (a Luo converter). Step-up or boost converters increase the voltage from their input (supply) to their output (load) while converting DC to electricity. The PWM generator, which is connected to the power source and produces PWM pulses to modify the signal in the LUO converter, is used to produce PWM pulses.
