Abstract :
Leakage currents are small, unwanted currents that flow from solar panels or wiring to the ground due to parasitic capacitance. These currents can reduce efficiency, create safety hazards, and cause interference. To reduce the leakage currents passive filters are used, to improve the power conversion by proper grounding. Passive filters acts like gates, blocking these unwanted currents allowing flow of current in one particular direction. A fuzzy logic controller acts like a smart system, constantly adjusting the solar panels based on conditions like sunlight and temperature to maximize energy production. Fuzzy logic controllers don't directly stop leakage currents, instead optimize the solar panel system's operation to minimize factors that contribute to leakage currents. By intelligently managing the system, they can also lessen the impact of any existing leakage. This smart control optimizes performance even with changing weather conditions, ensuring the system consistently generates as much power as possible. Proper mitigation of leakage currents using of fuzzy logic controller are key to maximizing both the safety and efficiency of a solar PV system.
