摘要：

A　driving　circuit　in　transient　electromagnetic　instrument　is　designed　based　on　CPLD.　In　the　circuit,　the　transmitting　waveforms　are　generated　by　CPLD　and　the　synchronization　is　implemented　by　wired.　In　addition,　the　gate　driver　IR2110　for　the　power　switch　devices　is　employed　to　control　the　high-power　MOSFET　for　driving　the　H-bridge.　Compared　with　the　reference　circuit,　the　generated　waveform　of　the　proposed　circuit　has　short　turn-off　time　and　high　current.　The　testing　results　show　that　the　proposed　circuit　has　a　better　performance　on　driving　the　coils.　The　transmission　delay　is　reduced　and　the　measuring　accuracy　is　further　improved　to　deepen　the　detecting　depth.　©　2012　Springer-Verlag　GmbH.
