    • A high voltage transformer for controlling inductance leakage used for a multiple lamp driving system includes at least one wire frame, a first winding, a second winding, a first magnetic unit, and a second magnetic unit. There is a receiving space in the wire frame for receiving the first magnetic unit, and a first region and a second region is formed on its surface. The first winding and the second winding are individually wound at the first region and the second region. The second magnetic unit is covered on the side of the wire frame. On an appropriate location of the bottom of the second magnetic unit, a transverse beam extends. Thereby, the transverse beam 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.
    • 用于控制用于多灯驱动系统的电感泄漏的高压变压器包括至少一个线架,第一绕组,第二绕组,第一磁单元和第二磁单元。 在线框架中具有用于接收第一磁性单元的接收空间,并且在其表面上形成第一区域和第二区域。 第一绕组和第二绕组在第一区域和第二区域单独地卷绕。 第二磁性单元被覆盖在线框架的侧面上。 在第二磁性单元的底部的适当位置,横梁延伸。 由此,横梁通过第一绕组和第二绕组以及由AC产生的高压磁通路完全分离在第一磁性单元上产生的低压磁通路径。

    • A circuit making use of a push/pull-type control chip to drive a half bridge-type inverter circuit connects a drive circuit to a conventional half bridge-type inverter circuit, and has a push/pull-type control chip having two output terminals, a drive circuit having two input terminals and two output terminals, and a half bridge-type switch assembly having two electronic switches. The two input terminals of the drive circuit are connected with the two output terminals of the push/pull-type control chip and controlled by the push/pull-type control chip. Each of the two electronic switches of the half bridge-type switch assembly has a control terminal, which is connected to one of the two output terminals of the drive circuit and driven by the drive circuit for converting a DC power source into an AC power source sent to the primary side of a transformer.
