As　the　power　density　of　power　module　increases,　the　components　have　to　be　placed　more　and　more　closely　and　the　near　field　coupling　will　become　more　obvious.　An　integrated　coupling　inductors　scheme　had　been　introduced　by　utilizing　their　near　field　coupling　effects　among　inductors　for　multi-phase　VRM　application.　Some　considerations　were　taken　such　as　component　distance,　height,　air　gap　layout　and　partial　magnetic　path.　Moreover,　the　near-field　coupling　concept　was　extended　to　general　applications　with　multiphase　topology　and　coupling　structures　of　ladder　and　cluster　type　had　also　been　proposed.　Finally,　experiment　had　been　carried　out　for　verification.　©2009　IEEE.
