The main objective of this project is to obtain high efficiency in switched capacitor based Resonant Converter (SCRC). To obtain high efficiency, Zero Voltage Switching (ZVS) operation is used. The dc-dc converter (buck) will step down the input dc voltage to the given reference voltage. The Fuzzy controller will control the outputs which are voltage and current and those will be displayed in graph. The switching frequency of the dc-dc converter (buck) is set to 20 kHz for faster switching operation. Conventional dc-dc converters applied to battery chargers, dc power supplies, voltage regulator, fuel cells etc. include magnetic components such as inductors and transformers which occupy a large volume and also it produce non-negligible losses. By using SCRC, the inductor volume is reduced. Conventional dc-dc converters use PID controller. In this Project Conventional method has done and also fuzzy logic controller will be used. The expected output voltage for this proposed method will be 20% to 80%. This system is implemented in MATLAB Simulink software. This project is also providing some analysis and comparative assessment.
