我看到很多產品都用1個Y1電容.但是從EN61347-2-2看到必須用2個Y2 電容

good!
IEC61347-2-2 A1[2006-06-04] clause 8.2
In the case of capacitors which are connected between SELV-equivlent output and primary circiuts,one capacitor Y1 or two capaciors Y2 in series with the same value specified and tested according to Tables 2 and 3 respectively of IEC 60384-14 are to be used.
從這段可以知道是可以使用1個Y1電容來代替2個Y2電容的
