Design of a Vehicular 200-Kj Pulsed Power System for Electrothermal-Chemical Launch Experiment

This paper has designed a 200-KJ pulsed power system (PPS) for Electrothermal-Chemical Launch (ETCL). The PPS consists of pulsed power module, high voltage charger, remote control system and high power connector. Two independent 100-KJ pulse forming units (PFUs) are integrated in one pulse power module and are charged to the same voltage by one HV charger. In each PFU, a pulse capacitor, a semiconductor switch stack, an inductor, a dump system and a data acquisition system were integrated. The PFU was designed to achieve a peak current up to 50KA at a maximum charging voltage of 10KV. The high voltage charger was integrated into the pulse power module. The experimental data of PPS showed that output current meets the requirement.
