有原邊多繞組,副邊單繞組輸出的變壓器嗎?

是否推挽電路?

不是
原邊多個(gè)繞組互相隔離,且都是同名端.不是推挽

I did
I design a power with DC input and AC input, primary have two winding, one is for ac input(high dc voltage) one is for dc input(low dc input 9v ~16V), the dot is same, but the power switch of mos is selected by electronic circuit to sense the input is ac or ac,and this model is enter into mass production. so did you have any problem for this matter

two winding
Yes, one is for the bulk cap voltage as you know (ac input then rectify to DC voltage or come out by active power factor convertor), another is provided by DC input (9 ~16) as car or airplane.
