This　paper　introduces　integrated　control　technology　into　the　intelligent　control　for　AC　contactor.　Buck-Boost　circuit　is　transformed　to　design　an　intelligent　control　module　for　AC　contactor.　Pulse　skip　modulation　(PSM)　mode　is　applied　in　the　module.　With　the　smart　power　IC　as　the　core　of　hardware　circuit,　it　has　the　function　of　overload　protection　and　short　circuit　protection.　What＇s　more,　the　control　idea　of　closed-loop　feedback　switching　from　voltage　loop　to　current　loop　is　proposed.　Therefore　the　AC　contactor　can　start　with　voltage　loop　and　keep　with　current　loop　automatically　in　one　circle　topology　without　microcontroller.　It＇s　a　natural　transition　process　without　overvoltage.　The　module　works　without　auxiliary　power　supply　and　microcontroller,　compared　with　the　conventional　scheme.　The　module　features　small　volume　of　hardware,　low　power　consumption,　less　active　components　and　high　degree　of　integration.　In　addition,　the　simulation　model　of　AC　contactor　with　control　is　built.　The　control　circuitry　is　designed　in　Multisim　and　the　dynamic　model　of　contactor　based　on　magnetic　circuit　method　is　designed　in　LabVIEW.　Connecting　LabVIEW　with　Multisim　it　realizes　co-simulation　of　dynamic　model　and　control　module　of　contactor.　This　paper　analyzes　the　principle　of　control　circuit　and　property　of　contactor,　considering　the　inductance　changing　of　circuitry.　The　experiments　are　performed　to　verify　control　module.
