This　paper　presents　a　research　of　full　digital-controlled　AC/DC　converter,　which　consists　of　single　Boost　PFC　and　LLC　resonant　DC/DC　converter.　The　whole　control　system　structure　is　proposed　to　integrate　all　analog　control　functions.　By　digital　control,　it　can　reduce　the　system＇s　volume　and　costs,　improve　characteristics.　As　a　proof　of　this　design,　an　example　of　240W　AC/DC　converter　is　given.　The　experimental　results　show　that　the　design　of　AC/DC　converter　is　feasible.　©　2014　IEEE.
