摘要:

摘要:本文应用了一种新的隔离式三电平半桥双向DC/DC拓扑。双向DC/DC具有易实现软开关,功率双向流动,电气隔离,高可靠性以及具有完全对称的配置。和两电平双向DC/DC对比,本文中所选用的三电平半桥双向DC/DC可以更方便的用在高电压环境中,因为每个开关管所承受的耐压只有直流侧电压的一半。本文对该拓扑工作在双移相情况下作了详细的电路分析。仿真结果也证明了结果的正确性。

Abstract:

Abstract: A new topology of isolated three-level half-bridge bidirectional DC/DC converter is used. Ease of realizing soft-switching control, enabling bidirectional power flow, galvanic isolation, high reliability and having complete symmetry of configuration and so on, which are the common advantages of bidirectional DC/DC converter. Comparing to the two-level bidirectional DC/DC converter, the three-level half-bridge bidirectional DC/DC converter used in this paper can be more useful in high voltage application, because of the apparently decreased in switch stress. In this paper, detailed circuit analysis is made. Simulation results go with our conclusion which indicates the correctness of my research.
