摘要：Within renewable energy field, solar panel that principled at photovoltaic effect has been used as alternative energy. MPPT method is using to obtain maximum output power from solar panel if loads are fluctuate. MPPT that implemented use fuzzy logic in function to regulate on/off time of MOSFET in SEPIC converter by generating PWM signals. The results of testing provide load power at irradiance 1000 W/m2, 800 W/m2, 600 W/m2, and 400 W/m2 when using MPPT is close on power value of MPP better than direct-coupled method. Average value of power ratio with MPPT based on fuzzy logic is 70.833 % whereas direct-coupled is only 29.312 %.
