摘要

new DC-DC converter design for wide range input is proposed using GaN devices and integration technology. The topology is based on active-clamp flyback converter with some improvement on devices and operation methodology. Through 10V to 80V input voltage range, there are two outputs fixed at 15V meanwhile delivering up to 15W power each. To get a smaller volume a plan for embedded transformer is proposed with some simulation results. The open loop controlled converter is built and tested. Some design improvement is made following the test results and analysis.
