The kicker magnet design parameters of HLS full energy injection system upgrade are presented, several types of high voltage and high current pulse generator＇s circuit topologies for kicker magnets are performed, which are transmission line, simplified PFN （pulse forming network） and solid-state inductive adder type. Three basic equivalent circuit models of pulse generators are established and simulated by computer, their outer parameters are calculated with the universal circuit simulation software program-PSpice. The possibility of using solid-state switches and new magnetic material in high power pulsed modulators is analyzed. An emphasis is put on the new magnetic coupling solid state inductive adder pulse generator. The design of prototype based on IGBT switches, the circuit outline and waveforms of the basic cell circuit are presented. The results reveals that the inductive adder pulse generator meets the HLS injection upgrade demands . The pulse generator can be used for HLS injection system up- grade, and the rise and fall time of the output pulse is fast and the pulse width is able to be adjusted.
