Patent ID: 7301430

Claim:
A high voltage transformer for controlling inductance leakage, used for a multiple lamp driving system, comprising: at least one wire frame, wherein there is a receiving space in the wire frame and the surface of the wire frame forms at least one first region and one second region; a first winding wound at the first region of the wire frame; a second winding wound at the second region of the wire frame; at least one first magnetic unit installed in the receiving space of the wire frame; a second magnetic unit covering the side of the wire frame, wherein at an appropriate location of the bottom of the second magnetic unit, a transverse beam extends and is used for separating the first region and the second region; thereby, the transverse beam of the second magnetic unit fully separates the low voltage magnetic flux path produced on the first magnetic unit by the first winding and the second winding and the high voltage magnetic flux path produced by the AC.
