Comparison and Simulation of Full Bridge and LCL-T Buck DC-DC Converter Systems

The DC-DC Converter topologies have received increasing attention in recent years for Low power and high performance applications. The advantages DC-DC buck converters includes increased efficiency, reduced size, reduced EMI, faster transient response and improved reliability. The front end LCL-T in a buck converter is connected in sequence manner to improve the electrical performances and to reduce the switching losses. It futures several merits such as multi output capability and also will associate with one or two capacitors so has to improve resonant operations. This paper compares conventional buck converter and LCL-T type converter designed for low voltage and low power applications and simulation results are compared for both converters
