Abstract

This paper presents a study on the efficiency of DC-DC converter to charge/discharge lithium battery. The losses of switching device, magnetic components, output capacitor, diode, and snubber circuit are analyzed by considering the charge/discharge characteristics of the converter. Based on the loss analyses, efficiency simulation in charging/discharging process are performed.
