Hi experts,<\/p>\n

I have some question about winding loss of planer transformer.<\/p>\n

Below figures are my simulation model. <\/p>\n

as you can see the only different is the winding width is not the same, one is long and the other is short, and both have the same air gap.<\/p>\n

As my understanding, if I want to reduce the DCR(Low frequency resistance) I can add the width of winding to reduce the DCR, from the simulation result, it is accuarte to reduce the RDC after I add the width on primary side winding (orange color) and secondary side winding (green color).
<\/p>\n

Figure 2 has more larger width than Figure1, so the DCR will be smaller that will reduce the power loss on winding.<\/p>\n

below is my questions, after I check the loss from the MAXWELL result, although the RDC is reduced, but I find it also increase the Rac (high frequency resistance), so the AC loss is increased.<\/p>\n

May I know how to explain this phenomenon?<\/p>\n","protected":false},"template":"","class_list":["post-236364","topic","type-topic","status-closed","hentry","topic-tag-airgap-1","topic-tag-losses","topic-tag-transformer","topic-tag-winding"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["264007","186775"],"_bbp_author_ip":["23.48.209.109"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["804"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["236364"],"_bbp_forum_id":["27793"],"_bbp_engagement":["186775","264007"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["240352"],"_bbp_last_active_id":["240352"],"_bbp_last_active_time":["2022-11-10 14:03:43"]},"test":"b0441005ems-niu-edu-tw"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/236364","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/236364\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=236364"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
