Abstract (en)

A light-weight and compact vehicle mounting transformer capable of providing a required reactive voltage and stable loose coupling characteristics between the output side windings is provided. The vehicle mounting transformer 4 comprises a shell-type iron core 5, an input side winding 6 and output side windings 7 wound around the iron core 5 in a magnetically inductive relationship relative to each other, a magnetic member assembly 17 with air gaps disposed between the input and output side windings, and a second magnetic member assembly 18 is disposed between the output side windings 7 for a magnetically loose coupling therebetween. The second magnetic member assembly 18 comprises air gap-less magnetic member 15 disposed within the space 5d surrounded by the iron core 5 and an insulating member 16 insulatingly supporting the air gap-less magnetic member 15 relative to the iron core and the windings. <IMAGE>
