There is discontinuous input current or output current in most of the isolated DC-DC converter. If continuous current is required, generally we need to add additional bulky filter, which will reduce the system's power density. In this paper, the method of adding a built-in filter to the isolated converter to achieve a continuous input current was employed. The built-in filter is composed of transformer...
Based on the third generation of semiconductor material, GaN device becomes obvious candidate for new generation POL converters. With the development of integration technology, planar transformer is applied for miniaturization and high power density. LLC resonant converter with EPC eGaN FETs and planar transformer is studies in this paper. First, the difference of LLC resonant converter with eGaN...
This research studies the forces on the windings of transformer due to magnetic inrush current. These forces are compared with the corresponding forces due to short-circuit of the windings. Three dimensional finite element computation of three-phase power transformer is carried out based on the maximum permissible magnetic inrush current value where its amplitude is the same as the rated short-circuit...
