Peningkatan Kinerja Konverter Buck Boost Menggunakan Kontrol Logika Fuzzy.

Buck-boost converters are one of the important devices in power conversion applications that are capable of increasing or decreasing the voltage according to the load requirements. However, the main challenge in operating a buck-boost converter is maintaining the stability of the output voltage. The selection of PID control is one of the ways that can be used to keep the output voltage stable, in this study, buck boost with 12 volts input is used and PID control is set with several parameters that can reduce errors and stabilize the output voltage, the PID constant values are Kp = 2 and Ki = 0.2 with these parameters obtained less stable results with time rise = 72.45 ms and overshoot = 0.995 % for boost mode with voltage 24 volt output and time rise = 123.2 ms and overshoot = 0.995 % for buck mode with an output voltage of 5 volts. Thus, to maximize the system with a stable output voltage, a fuzzy logic control is used which has an adaptive time response and is able to adapt to load variations, the simulation results show that the output voltage of the fuzzy logic control has a time rise = 114 ms and overshoot = 0.761 % in boost mode and time rise = 104 ms with overshoot = 0.971 % in buck mode. The advantage of fuzzy logic control is that it is more optimal and able to improve system performance responsively compared to other conventional controls. [ABSTRACT FROM AUTHOR]
