Kicker power supply is one of the key components in the injection and extraction system of HIAF (High Intensity Heavy Ion Accelerator Facility, the 12th five-year national big science project). The PFN-Marx generator technology based on solid-state IGBT switch will be applied to HIAF-Kicker power supply. Hundreds of fast pulse signals are required to control these IGBTs. The PFN-Marx generator has many requirements for these control signals, such as adjustable pulse-widths and time-delay. The maximum value of adjustment accuracy of the pulse-widths and delay among multiple control signals need to be 10ns. In this paper, a fast pulse generator circuit based on an emerging ARM-embedded FPGA have been designed for HIAF-Kicker power supply. The test results show that the output performance of the fast pulse generator circuit meets the requirements of the PFN-Marx generator.
