摘　　要：通过对高频隔离三相DC-DC变流器进行建模,控制和设计,并在固定工作频率下进行对称和非对称控制,根据变流器工作过程对它进行稳态分析,并建立了一个DC-DC变流器模型为750 W、5 V/150 A,在不同的条件下进行测试,实验结果表明,提出的三相高频隔离DC-DC变流器可应用在较低的电压转换比、对负载和线路干扰有良好的隔离、调节和快速的动态响应的优点。In this paper, modeling, control and design of high-frequency isolated three-phase DC-DC converter is carried out under symmetrical control with fixed frequency operation and its steady state analysis is presented according to the description of the operation stages of the converter. A 750 W, 5 V/150 A prototype model of the proposed DC-DC converter is built and tested at different operating conditions. Based on experimental results under the control method, the proposed DC-DC converter can be used in applications which require very low voltage conversion ratio, isolation, good regulation against load and line disturbances, and fast dynamic response.
