“…However, during testing of the railgun system, the researchers discovered that the GTO thyristors were able to safely interrupt more than 7kA of current. 5 Unfortunately, the researchers did not have the opportunity to fully investigate the turn-off characteristics of the GTO and were unable to determine why the GTOs were able to interrupt more current than they were rated to interrupt. They recommended additional follow-on effort to investigate the GTOs and potentially determine the cause(s) for the increase in current blocking capability.…”

Inductive pulsed power supply (IPPS) is a promising type of power supplies for electromagnetic launch, but its advantage in energy density is strongly restricted by the primary power source. Fortunately, batteries become a suitable and practical choice for the primary source. In this paper, the working process of battery powering IPPS is analysed in detail. Various indicators of the charging performance are calculated, which are then proved to be irrelevant to most of the parameters of IPPS. Based on this, an optimization method for battery and IPPS system is proposed, in which the charging and discharging processes can be decoupled. And for the decoupled battery charging process, the bi-objective optimization model is suggested. Several examples illustrate the feasibility and effectiveness of the proposed optimization methods. In order to further improve the performance of the battery and IPPS system, the inherent time constant of the inductors and the output power density of the battery cell should be increased.

“…To date, there is much literature about pulsed power technologies with different technical approaches [4][5][6][7][8][9][10]. To meet both the high-energy density and high-power density requirements of the electrical pulse energy supply chain for the electromagnetic launch, a hybrid energy storage technology is widely utilized [2,[11][12][13][14][15]. The most common scheme is the battery-pulse capacitor-based hybrid energy storage system [16][17][18][19].…”

The battery-pulse capacitor-based hybrid energy storage system has the advantage of high-energy density and high-power density. However, to achieve a higher firing rate of the electromagnetic launch, a shorter charging time of the pulse capacitor from the battery is needed. A new optimization model by formulating the charging time problem as a constrained optimization problem is presented. Unlike existing algorithms, the proposed model can find the globally optimal solution. The circuit parameters are optimized through the Enumeration algorithm to minimize the total charging time of the pulse capacitors from batteries. The simulation results show that the charging time of the proposed algorithm is shorter than the compared methods. Furthermore, a better solution could be obtained by canceling the constraint on the first peak of the charging current of the compared methods, which makes the circuit design more flexible for the hybrid energy storage system in the electromagnetic launch.
