High Frequency Soft Switching Boost Converter with Fuzzy Logic Controller

in this paper, a high frequency soft switching boost converter is proposed along with a fuzzy logic controller. Usually, conventional boost converters the efficiency is highly reduced due to hard switching. Due to this this reason here it introduces the soft switching method in which the boost converter is implemented with a simple auxiliary resonant circuit (SARC). The switches in this adopted circuit will turned on at zero current condition (ZCS) by resonant inductor and turned off at zero voltage condition (ZVS) by resonant capacitor. And hence the switching loosed will be greatly reduces and efficiency increases. Compared to the open loop circuit, closed loop will provide more efficient output. Fuzzy Logic Controller is used to provide the closed loop. The simulation is done at MATLLAB @ Simulink software.
