Abstract
A transformer apparatus reducing magnetic field interference includes an iron core, a first side coil unit, a second side coil unit, a first current transmission line, a second current transmission line and a third current transmission line. Both the first side coil unit and the second side coil unit are wound around the iron core. The first side coil unit is connected to the first current transmission line and the second current transmission line. The second current transmission line is connected to the third current transmission line. The first current transmission line includes a first current conduction segment and a first insulation layer. The first insulation layer coats the first current conduction segment. The third current transmission line includes a second current conduction segment and a second insulation layer. The second insulation layer coats the second current conduction segment. The second insulation layer touches the first insulation layer.
