Abstract

In era of technology, rapid advancement of low-loss converter design has become a major challenge to designers. Synchronous Rectifier Buck Converter (SRBC) is one of them. It is perceived that the development of low power converters in future must have the capability to operate in megahertz switching frequency. In this work, the study and evaluation of parameters in SRBC for two conditions: Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) will be carried out. This will help in search of the optimized parameter values for both conditions. This project will be based on simulation circuit using PSPICE software. The simulation will involve the study of the data sheet, circuit operation and the fundamental of SRBC circuit. Then, the results will be evaluated in terms of its losses, ripple and also body diode conduction. At the end of the project, the comparison between Conventional SRBC with Adaptive Gate Drive (AGD), Compensator and AGD, MOSFET Parallelism and Maximum Power Point Tracking (MPPT) are done to analyze on the performance of the circuit. It is found that the optimized parameter values for CCM are £=15 11H, C=0.625 11F and R=3.5 n while for DCM the value are L=l 11H, C=9.375 f.IF and R=4 n. Comparatively, it is proven that the Conventional SRBC is best when implementing using MPPT controller due to its ability in improving the output voltage and current and also reducing the losses which are voltage ripple, current ripple and body diode conduction.
