Title: Pulse power source
Inventor: INATOMI YUTAKA
IPC: H03K17/00
Filed: 1992-10-09
Abstract: PURPOSE:To reduce the control voltage of a semiconductor switch and to miniaturize a device with respect to the pulse power source which obtains a high- voltage large-current pulse from the semiconductor switch and a saturable transformer or the like. CONSTITUTION:A pulse current flows from an initially charged capacitor C0 to a step-up transformer T when a semiconductor switch SW is turned on, and a capacitor C is charged to a high voltage with the pulse current boosted by the step-up transformer by the boosting operation of a saturable transformer ST1. A high-voltage large-current pulse from the capacitor C1 to a discharging tube DT is obtained by the saturation operation of the saturable transformer ST1. The semiconductor switch SW reduces the control voltage by boosting of the step-up transformer T, and the saturable transformer ST1 reduces the boosting ratio to raise a pulse compression ratio after saturation.
