IMPLEMENTASI PENGONTROLAN TEGANGAN KELUARAN DC STEP-UP ZETA CONVERTER DENGAN VARIASI TEGANGAN INPUT DARI SINGLE PV MENGGUNAKAN LOGIKA FUZZY

Abstract

The solar panel is a device that functions as a producer of electrical energy by converting solar energy into electrical energy but have several disadvantages, one of which is the non-constant output voltage due to the influence of light intensity and surface temperature of the panel. In this research, Zeta  Converter will be designed and implemented as a tool that plays a role in maintaining the output voltage of solar panels to remain constant at 24V DC, with Fuzzy Logic Control as a method in controlling PWM switching. The results obtained from this study are that zeta converter can keep the output voltage of solar panels constant at a value of 24V, with a low ripple voltage and overshoot. The fuzzy logic method used can produce a constant output voltage with a rise time around 5 seconds. The efficiency obtained from this converter hardware is around 70% - 73%.
