Abstract:

电感储能型脉冲电源由于具有较高的储能密度和相对容易实施等优势而倍受研究者的关注。Meatgrinder和XRAM是构成电感储能型脉冲电源的两种基本拓扑单元。其中,由多个电感线圈串联充电、并联放电构成的XRAM拓扑在结构上具有较强的拓展性,易于实现模块化。本文将构成XRAM电路的多个电感定制成为相互层叠的多个空心平面螺旋线型线圈结构,使电感线圈间具有强耦合作用。与原有结构相比,在相同储能时体积更小。理论分析和初步试验说明了电感间的强耦合作用不会弱化电路的电气性能。最后,讨论了利用这种含有强耦合电感的XRAM拓扑构建100kJ能级模块的方案,并计算了储能密度,突出了其优越性。
