High-power Z-pinch experiments use multi-channel circuits in parallel way to meet the demand of the load on current.In order to achieve an effective superposition of the pulsed power,we need to accuracy control the timing of each pulsed power system under the stability requirements.Synchronization pulse generation system with multi-channel and high-precision helps to solve this problem .This system was designed through the accurate analysis of sequential logic and the ingenious usage of FPGA,so that it can work stability in the clock of 200MHz when it provides 16 trigger signals and 16 command signals at the same time.This design not only well meet the requirements of different experiments,but also ensure the stability of the system,and improve the accuracy,too.
