Abstract

The present invention provides a transformer, which comprises a winding rack, an iron core set, and a coil set. The winding rack is provided with a center hole extending along a longitudinal direction, a first winding portion formed on one side, a second winding portion formed on the other side, at least one third winding portion formed between the first and second winding portions, and a plurality of lead terminals located at both ends. The coil set is provided with a primary magnetic excited coil, a secondary sensing coil wound on the second winding portion, and an auxiliary coil wound on the third winding portion. The winding method of the auxiliary coil substantially corresponds to the primary magnetic excited coil and the secondary sensing coil in the vertical direction. Thus, the present invention could adjust the magnetic flux leakage, and further employ a leakage inductance adjustment unit to adjust the auxiliary coil for controlling the amount of magnetic flux leakage and obtain the required amount of leakage inductance by the adjustment of magnetic flux leakage.
