介绍了一种基于单相双有源桥式拓扑结构的高功率、高功率密度DC/DC功率转换器的分析、控制和性能。对于高输出电压，在千伏数量级，考虑级联输出结构。讨论了吸收电容和磁化电感对软开关区域的影响以及各种控制策略。给出了电流型控制器的计算机仿真结果。由于变压器的漏感是主要的能量传递元件，因此采用了特殊的变压器设计技术来仔细控制这一参数。给出了一台输入电压为1600VDC的50kW、50 kHz样机的版图。并给出了一些实验结果。
The analysis, control, and performance of a high-power, high-power-density DC/DC power converter that is based on the single-phase dual active bridge topology is described. For high-output voltages, on the order of kilovolts, a cascaded output structure is considered. The impact of snubber capacitance and magnetizing inductance on the soft switching region and various control strategies are discussed. Computer simulation results of a current mode controller are presented. Since the leakage inductance of the transformer is the main energy transfer element, special transformer design techniques are utilized to carefully control this parameter. The layout for a completed prototype 50 kW, 50 kHz unit operating with an input voltage of 1600 VDC is presented. Some experimental results are also presented.>
