Abstract

Buck converter high side switching configuration can affect substantial reduction in power converter performances, allowing considerable higher power losses. This paper investigates a buck topology that achieves improved perfomance of direct current dc-dc buck converter by increasing duty cycle and by selecting low side switching configuration to reduce the power losses . The performance of buck converter for both high side switching configuration and low side switching configuration is analyzed. The design of buck converter circuit are investigated. The experimental results demonstrate the feasibility and high performance of the dc- dc buck converter. The analysis is verified experimentally using LVDAC - EMS.
