چکیده
In this paper, Series-Parallel LLC type of DC DC resonant power converter configuration that uses a Compression Network (CN) has been proposed. The purpose of this CN is to maintain desired current waveform over entire range of voltage operating condition. The proposed circuit maintains high efficiency over wide range of power level. Also, the closed loop PI and fuzzy controller is used on the input side of the LLC resonant tank. The input 40V is boosted to produce output voltage of 235V with the help of ZVS boost converter with 140 kHz resonant frequency. Furthermore, performance parameters such as Voltage gain, Efficiency, Total Harmonic Distortion (THD), Switching losses and Voltage ripples was calculated. It has been proved that the proposed method has more efficiency and low losses than the conformist one. The simulation is done by using MATLAB / SIMULINK software. The simulation results of CN DC-DC Resonant Converter with FUZZY and PI controllers were compared and investigated various parameters.
