Abstract
The structure of a high voltage transformer is disclosed. The transformer structure has a magnetic core, a multi-layer printed circuit board (PCB), a conductor winding, a voltage doubling rectifier means, a magnetic means, a supporting means, and insulated oil. The multi-layer PCB has spiral coils used as a secondary winding. A conductor windings is used as a primary winding. The voltage doubling rectifier means includes an anode voltage doubling rectifier circuit and a cathode voltage doubling rectifier circuit which are respectively formed on a first and a second insulated boards. The two voltage doubling rectifier is used to increase the voltage gain. The magnetic means has a top magnetic cap and a bottom magnetic cap. The mullet-layer PCB and the voltage doubling rectifier means are interposed between the top and the bottom magnetic cap for decreasing the leakage magnetic flux. The breakdown distance can be maintained in an appropriate distance by using the supporting means. The insulated oil serving as an insulated material is filled into the transformer structure to increase the durability of breakdown voltage.
