Abstract

Capacitor charging power supply (CCPS) is one of the most important components of a pulsed power system. The CCPS studied in this paper is used in power conditioning systems for Laser Nuclear Fusion. With a view to enabling multiple CCPSs to work concurrently in an environment of high voltage, high power and strong electromagnetism, this paper carries out a profound and systematic research into the characteristics of a capacitor charging power supply, including charging rate, harmonic features, efficiency and voltage precision, etc. Furthermore, some measures to improve the characteristics of CCPS are put forward. The advantages of high charging rate, low harmonic, high efficiency and accurate charging voltage are proved by the results of experiments and the performance in practical operation on a 23.5 kV, 50 kW, 4400 μF CCPS.
