<P align=right>——高永生 應用工程師，世強電訊 </P> <P> 隨著對家用電器消費觀念的不斷變化，消費者對抽油煙機的要求也越來越高。通常吸抽油煙機轉速靠人工調節，因此為了達到最佳排油效果及節能目的，往往需要使用者多次人工干預。因此，為了使抽油煙機可實現自動調速、降低噪音、解放人力并最大限度地節能，瑞薩電子（本文涉及產品主要為瑞薩電子原NEC部分）推出了一系列變頻控制專用的8位MCU。本文主要介紹了8位MCU――uPD78F0712的主要特點及基于該產品的變頻抽油煙機解決方案。 </P> <P><STRONG> 變頻抽油煙機的特點</STRONG> </P> <P> 抽油煙機變頻的目的是為了通過調整抽油煙機上的帶動風扇的電機轉速，進而根據油煙量的大小調整油煙抽吸的快慢。優良的調速和節能效果使得變頻抽油煙機在性能上明顯優越于傳統的抽油煙機，而變頻抽油煙機根據具體的變頻技術有不同的分類和性能特點，如表1所示。 </P> <P><STRONG> 表1 ：各種變頻抽油煙機的關系和特點</STRONG> </P> <DIV align=center> <TABLE class=MsoNormalTable style="MARGIN: auto auto auto -22.8pt;
