摘要
针对28 V直流机载供电系统中电源宽范围输入的特点,提出一种Buck+电流馈电交错正激的两级拓扑结构。着重分析了电流馈电交错正激的工作过程,解决了宽范围输入DC/DC变换器高效率转换和系统稳定的问题。样机电路测试结果验证了所提线路结构的可行性。
According to the characteristics of wide range input in 28 V DC power supply system of airborne,a two-stage topology with buck and current-fed interleaved forward was proposed.The working process of current-fed interleaved forward was analyzed.The problem of high efficient conversion and system stability for the wide rang input DC-DC converter was solved.The prototype test results verify the feasibility of the circuit structure.
