Design of compact high-voltage capacitor charging power supply for pulsed power application

The pulsed power supply (PPS) with capacitor energy storage is the integral part of launch system, which is often used as energy storage element for electrothermal-chemical (ETC) launch, electromagnetic launch (EML), and other new-concept launch technology. In order to make capacitor charged rapidly, a novel capacitor charging power supply (CCPS) has been developed in this paper characterized by compact size, high charging power density and short charging time. Through comparison and analysis, a full-bridge series resonant zero current switching charging circuit, dry-type transformer, active cooling technology, anti-jamming technique, high integration structure design technology have been adopted. By analysis and calculation, the CCPS, which can satisfy quick and step by step charging to capacitor, with the charging current of about 5A, maximum working voltage of 12kV and charging voltage error of below 0.5%, has been designed. Finally, the CCPS has been developed and verified to be stable and reliable in the system by charging a 250kJ PPS module.
