A Closed Loop Fault Tolerant Series Resonant Dc-Dc Converter

Abstract

In this project we are implementing the Series-Resonant dc-dc converter (SRC) which is widely utilized in the power supply from the telecommunications, wireless power transfer for electrical vehicle and high voltage power supplies. Here we are developing the fuzzy controller for the better performance. Fuzzy controller is the most suitable for the human decision-making mechanism, providing the operation of an electronic system with decisions of experts. Therefore in the reconfiguration method of the SRC which is performance for the cases of failure in one semiconductor, which is used to decreases the requirement of the redundancy. According to the proposed scheme the full bridge will be depend upon the SRC which can be reconfigured in the half bridge topology in order to converter the operation without the failure of one switch. According to the demerits of the technique, the output voltage a drop which is half of the original value. Moreover a novel reconfiguration rectifier which is depends upon the voltage doubler metholody which is proposed technique which is used to keep the output voltage constant after the faults. By utilizing the simulation results we can verify the proposed system which confirms the effectiveness of the proposed approach.
