This　paper　proposed　a　no-arc　control　topology　of　intelligent　contactor,　which　was　suitable　for　AC　/　DC　circuits.　The　control　topology　combined　with　the　advantages　of　the　existing　main　AC　/　DC　arc-quenching　technologies,　based　on　the　type　of　main　circuit＇s　power,　it　was　adaptive　to　enable　application　program.　The　topology　contains　the　advantages　of　the　hybrid　switching　technology　and　the　forced　zero-crossing　technology　to　realize　no-arc　motion　of　contact　in　DC　system.　The　arc　extinguishing　methods　were　not　limited　by　the　influence　of　the　action　of　the　electromagnetic　mechanism　by　introducing　the　feedback　signal　of　contact　current.　The　application　of　phase-selection　closing　in　electronic　switch　which　could　effectively　inhibit　the　inrush　current　in　AC　system,　in　the　mean　time,　zero-current-breaking　technology　was　used　to　realize　no-arc　breaking　of　contact.　The　action　process　of　contactor　was　optimized　by　combining　the　rapid　demagnetization　circuit　of　electromagnetic　system.　The　working　principle　of　the　proposed　circuit　topology　was　analyzed　by　simulations　and　experiments,　and　the　effectiveness　of　the　proposed　scheme　was　verified.
