The　waveform　of　lightning　protection　pin　injection　test　for　airborne　equipment　is　a　combination　wave　in　which　the　open　circuit　voltage　waveform　is　the　same　as　short　circuit　current　waveform.　For　such　class　of　combination　wave,　a　novel　combination　wave　generator　circuit　was　proposed　based　on　the　linear　RLC　circuit　of　impulse　current.　The　relationship　between　the　time　of　peak　value,　the　peak　current,　the　time　of　half　peak　value　and　damping　coefficient　parameter　of　the　circuit　was　studied.　A　design　method　was　proposed　for　combination　wave　circuit　which　the　time　of　peak　value　and　half　peak　value　serve　as　target　parameters.　The　circuit　parameters　of　lightning　protection　pin　injection　test　generator　for　airborne　electronic　equipment　were　obtained　by　calculation　and　simulation,　taking　account　of　the　influence　of　the　stray　parameters.　Simulation　results　show　that　the　output　waveform　of　the　generator　designed　can　meet　RTCA/DO-160G　standard　requirements,　and　the　generator　could　be　used　in　lightning　protection　pin　injection　test　for　airborne　equipment.　©,　2015,　Beijing　University　of　Aeronautics　and　Astronautics　(BUAA).　All　right　reserved.
