Title: Pulse generating device
Inventor: KIDO SHOJIRO
IPC: H05B41/18
Filed: 1989-12-25
Abstract: PURPOSE:To efficiently increase the pulse voltage on the secondary side of a transformer by connecting a first capacitor in parallel to the series connection of a second capacitor connected in parallel to a discharge gap and the transformer primary side, and discharging the charged voltage of the second capacitor by the discharge gap. CONSTITUTION:In the pulse generator circuit of a high voltage discharge lamp, first and second capacitors 2, 5 are charged by a power source 1. When the charged voltage of the capacitor 5 is reached to the discharge starting voltage of a discharge gap Vgap, discharge is started, and the charge of the capacitor 5 is discharged through the gap Vgap to output a pulse voltage from the secondary side of a transformer 3. In this case, the charge of the capacitor 2 is discharged through a coil 3a and the gap Vgap. As the voltage drop of this gap Vgap is reduced by the discharge of the capacitor 5, the voltage on the primary side of the transformer 3 can be increased. Thus, the pulse voltage on the secondary side can be efficiently increased.
