Optimization of Energy Transfer Efficiency for Pulsed Power Supply

In this paper,the optimization of sequential discharge was taken as the study object for a pulsed power supply system in electromagnetic launch.In order to improve the launching efficiency of the projectile with fixed mass and velocity,a sequential optimization method was proposed based on pattern search.Firstly,taking the initial charging voltage and discharge time sequence of the pulse capacitor bank as the optimization parameters,the multi objective problem was transformed into a single objective optimization problem by the constraint model method.And then,an iterative pattern search algorithm was used to optimize the problem,obtaining the required optimal results.Finally,the results were analyzed and compared with the results published in other literature.Results show that,the launch performance can be improved,validating the feasibility of the proposed method.And the results of actual emission experiment show that,the efficiency of this method can be increased by 7%.
