Patent attributes
The invention relates to a high voltage transformer having a double symmetric winding arrangement. The transformer comprises a closed core (10) having a first and a second leg (12, 14), a first and a second coil member (16; 18) having a first end, a second end and a middle section. Each coil member (16; 18) is wound with a first and a second primary winding (Prim 1, Prim 2 and Prim 3, Prim 4) and a first and a second secondary winding (Sec 1, Sec 2 and Sec 3, Sec 4), the first primary winding (Prim 1, Prim 2) being disposed at the first end and the second primary winding (Prim 3, Prim 4) at the second end of each coil member (16; 18) respectively. The first secondary winding (Sec 1, Sec 3) of each coil member (16; 18) is wound in the direction of the first end starting from the middle of the coil member, and the second secondary winding (Sec2, Sec 4) of each coil member (16; 18) is wound in the direction of its second end starting from the middle of the coil member, the winding direction of the first secondary winding (Sec 1, Sec 3) being opposite to the winding direction of the second secondary winding (Sec 2, Sec 4), and a first electric connection (HV12, HV34) being disposed in the middle of each coil member (16, 18).
