Abstract
The paper introduces a TTL digital circuit, which is designed as the trigger control system of high power pulse source, and presents the development of a high-voltage pulse source. In the source, the TTL circuit operated after the optical isolation circuit and power driver, and outputs pulse signals to drive MOSFET, which controls the pulse signal output from high-voltage switch. The source can outputs pulses with voltage of 5 kV, pulse-width larger than 200 μs and fall-time less than 30 ns. Besides long-distance control and local control mode, it also includes inner trigger and external trigger (one electric signal and one optical signal as the trigger). A series of experiments have been conducted to validate the design, and the one-shot trigger results are presented.
