A PC 200-1.5 Peaking Capacitor for an Output-Power Increase in the LTD-100R Stage

A compact low-inductance capacitors PC 200-1.5 with a 1.5-nF capacitance and with pulsed charging up to 200 kV has been designed. The PC 200-1.5 capacitor uses combined paper-film insulation with castor oil impregnation. To decrease edge effects in the capacitor, the insulation in the region of the sharp edge was divided into thin layers by means of capacitor plates displaced with respect to each other to a given value. The PC 200- 1.5 capacitors have been tested as peak capacitors in a stage of the high-power pulse transformer LTD-100 R [1] that provided an increase in its output power by ~25%. The lifetime of the capacitors is longer than 2- 10³ pulses.
