Abstract
In this paper, a study was conducted on the miniaturization of an e-Mobility battery charger module using GaN-FET. GaN-FET is one of the types of WBG devices, and it is a device that exceeds the performance of existing Si power semiconductors. In particular, GaN-FET has the advantage of small packaging size and high switching frequency operation, which is advantageous for miniaturization of power converters. Therefore, a bidirectional DC/DC converter module for e-mobility charging using GaN-FET was developed. To apply to the converter to be developed, analysis is performed on the characteristics of GaN-FET, and after manufacturing a prototype of a bidirectional DC/DC converter module, the efficiency and temperature data of the power converter are analyzed to verify its feasibility.
