Özet

Luo converter, a high voltage gain converter, shows a higher voltage gain and a lower output voltage ripple compared to conventional boost DC-DC converters. Luo converters perform voltage gain using a voltage lift method. Voltage gain is adjusted thanks to various circuit topologies using voltage lift method. Unlike linear circuit topologies, it is often difficult to model and control DC-DC converter circuits due to their switched structure. Conventional controllers such as PI, PD and PID remain inefficient in terms of controlling non-linear systems. Therefore, fuzzy logic based modern and intelligent controllers are needed with a view to improve the performance of non-linear systems. The present study proposes a PI and an Interval Type-2 Takagi-Sugeno-Kang Fuzzy Controller (IT2TSKFLC) for Luo converter with a positive output self-lift (POSLLC) circuit topology. MATLAB/Simulink was used to analyze the dynamic performance of these controllers.
