Abstract:Solid-state pulsed power is a hotspot in the research of pulsed power. A multi-channel trigger control system，which is applied to the solid-state modulator，has been designed and tested. Under the control of Field Programmable Gate Array(FPGA) and Micro Control Unit(MCU)，the trigger signal features a high pulse-repetition rate in burst mode，while the pulse width and frequency of every sub-pulse can be adjusted individually in real time. Between the trigger system and the power system, optoelectronic isolated circuit is adopted to reduce the interference of high power system on the low power system. The generator shows certain distinct advantages as convenient operation，steady run，simultaneous multi-channel output and so on. The generator can output 240 synchronic trigger signals at most，and the maximum of 4 pulses burst. The design of the signal generator and the measured data of performance are presented in this paper.
