The Capacitors Division at Sandia National Laboratories has for many years been actively involved in developing high reliability, low-inductance, energy-storage, pulse-discharge capacitors. Development has concentrated on two dielectric systems; mica-paper and Mylar (both dry wrap and fill and FC40 liquid impregnation). Continuous design improvements are constantly being sought. For pulse discharge usage lowering the capacitor inductance can improve circuit performance. This paper describes recent efforts to improve the efficiency of low-inductance, mica-paper capacitors by reducing the inductance through optimizing the component geometry. The study focused on a 0.2 {mu}F, 4000 V mica-paper extended-foil capacitor design. The experimental matrix was a two-level, three factor with center points design, and was replicated four times to give reasonable statistics. The factors were the capacitor width, capacitor length, and electrode width, and with response functions of capacitor inductance and circuit performance. The capacitor inductance was measured by the resonance technique, and the circuit performance was evaluated by peak (discharge) current and rise time. Results show that the inductance can be minimized by choice of geometry with accompanying improvements in circuit performance.
