Surge voltage generator with capacitors charged via resistors - using transformer coupled to spark gap cascade and with selectable output tappings

摘要

The surge voltage generator produces voltage pulses whose amplitudes can be altered to suit different applications but whose pulse energy remains constant despite the changes in amplitude. A transformer has its primary tappings coupled to a bank of capacitors, forming a series cascade with spark gaps and charged from a high voltage source, e.g. 8 kV, overcharging resistors. The transformer secondary winding has several output tappings. The selectively tapped transformer enables a large range of pulse amplitudes with constant energy to be selected. The energy can be altered by altering the widths of the spark gaps. This arrangement permits wide division of the tapped surge voltages.
