【Abstract】 The directly driven power supply system for high energy pulsed lasers mainly consists of an active compensated alternator(ACPA) and its flashlamp load. Unconventionally, the ACPA replaces the capacitor groups to discharge to the flashlamp pump directly. This paper investigates into the mathematic model of the ACPA with flashlamp load, and the relationships of both of the parameters are analyzed to match up. Then, based on the performances of the flashlamp load, a design process of ACPA prototype is proposed. The finite element analysis(FEA) is performed basing on to the ACPA prototype with the assistance of Ansoft maxwell, and the electromagnetic properties are estimated.Meanwhile, the system is modeled in Matlab/Simulink to analyze the electrical output performance of the flashlamp load. The simulation results prove that the proposed method can be correctly and conveniently applied in the analysis and design of the directly driven power supply system. It can also be extended to the power supply systems which consist of other types of generators indivdually their specific loads.更多还原
