Abstract：Inductors are the core elements in inductive pulse power supplies (IPPS). Their structure and parameters directly affect the performance of IPPS. The key element of inductor designing is to acquire the highest energy density. Inductors with high quality factors, such as Brooks coils, have the significance of high energy density. But due to different calculation methods of inductor energy density, Brooks coils do not necessarily have the highest energy density. Therefore, this paper indicates that, for the inductor design, the air-core flat spirals of strip coils (AFSSC) should be considered firstly, and after the parameters traversal of AFSSC, the inductors with the highest energy density can be calculated and found out. The accuracy of the method is verified by experiments. Finally, this article compares the optimization results of the proposed method and the Brooks coil parameters, and verifies the advantages of this method in enlarging the energy storage density.
