Abstract

In this paper, a 1.8kW,200V-310V/12V-15V, 700kHz DC-DC converter with high power density of 8.1kW/L (132.7W/in³) is developed for electric/hybrid vehicle application. In order to achieve high power density, GaN-based transistors at 700kHz switching frequency are applied to reduce passive component volumes. Furthermore, reduction of planar transformer size is achieved by applying the concept of the matrix transformer with flux cancellation. The characteristics of the 1^st prototype and the 2^nd prototype considered to improve the power density are covered and the design considerations of the gate driver for a high switching frequency of 700 kHz are covered. A three-dimensional (3D) Maxwell FEA simulation results are presented to give an accurate estimation of the core loss and flux distribution of the magnetic components and experimental results are also provided from a 1.8kW prototype.
