The design and operation of a compact high-voltage, high pulse repetition frequency trigger generator

A high-voltage trigger generator has been developed to trigger an in-line plasma closing transfer switch. The trigger generator is capable of producing 70 kV voltage pulses, having a rise time and duration of 10 and 60 ns respectively. It uses a stacked Blumlein cable generator fired using a triggered corona stabilized (TCS) switch and is fully controllable in frequency from single shot up to 10 kHz in a burst mode. The device is very compact, portable and is operated via a fibre optic link from a solid state pulse generator. The trigger generator can also be used as a fast high-voltage, high peak power and high-frequency driving device.
