Aim　at　adaptive　CMOD　for　electromagnetic　mechanism,　strategy　has　been　designed　to　widen　the　input　voltage　based　on　existing　wide　voltage　CMOD.　CMOD　is　divided　into　several　submodules　according　to　their　function.　Submodule　can　work　independently,　meanwhile,　cooperation　among　submodules　is　allowed　to　output　exciting　signal　for　various　contactors.　Combining　current　closed-loop　control　method　with　intelligent　control　strategy,　software　control　scheme　gives　CMOD　the　ability　to　fit　unknown　and　uncertain　system　in　order　to　allow　contactors　to　work　on　different　working　condition　and　load.　Further,　a　voltage-adaptive　CMOD　for　electromagnetic　mechanism　is　designed,　simulation　and　experiment　shows　that　the　CMOD　can　control　various　contactors　work　within　the　expectant　voltage　range.　©　2019　IEEE.
