The　multi-pulse　large　magnetic　moment　transmitting　is　one　of　its　key　technologies.　However,　a　few　topologies　have　been　reported　in　the　literature.　The　high-power　multi-pulse　current　source　circuit　suitable　for　HTEM　transmitter　system　is　presented　in　this　paper.　Through　the　switch　matrix　composed　by　IGBT,　the　circuit　uses　the　LC　resonance　principle　to　achieve　the　release　and　recovery　of　transmitting　energy,　thus　producing　the　main　pulse　of　the　large　current　and　secondary　pulse　steep　edge.　The　charging　circuit　is　designed　with　constant　power　control　and　soft　switching　technology　to　replenish　the　capacitor　energy　gap.　The　formula　of　the　circuit　parameters　is　deduced　by　the　analysis　of　the　circuit　working　process.　In　order　to　evaluate　the　performance　of　the　proposed　circuit　topology,　the　circuit　simulation　is　carried　out　by　using　Matlab/Simulink　software　and　a　prototype　circuit　is　built.　The　results　show　that　the　proposed　circuit　can　realize　multi-pulse　current　waveform　output　under　inductive　load,　and　it　has　the　characteristics　of　simple　structure　and　flexible　control.　©　2017　IEEE.
