Nuclear　magnetic　resonance　logging　transmitting　circuits　must　face　the　harsh　operating　environment　of　high　voltage　and　high　frequency.　To　reduce　the　voltage　and　current　tolerated　by　the　switching　devices　in　the　circuit　and　minimize　the　circuit　loss,　a　high-frequency,　high-voltage　pulse　transmitting　circuit　based　on　a　two-stage　full-bridge　structure　is　designed　in　this　paper.　A　new　strategy　for　pulse　excitation　oscillation　is　proposed.　The　proposed　strategy　is　based　on　the　decision　to　end　the　excitation　at　the　moment　of　peak　voltage　and　the　condition　for　limiting　peak　charging　current　(3.2).　Finally,　the　circuit　topology　and　excitation　strategy　proposed　to　achieve　the　overall　optimal　performance　of　sustained　voltage　oscillation　with　a　peak　voltage　of　1180　V,　precisely　matching　the　transmitting　frequency　of　481　kHz　and　suppressing　the　charging　current　below　10　A.　©　Published　under　licence　by　IOP　Publishing　Ltd.
