Flat high-voltage impulse transformer |
摘要 |
A flat high-voltage impulse transformer is proposed, which can be used in conjunction with a high-intensity discharge (HID) lamp to provide a high-magnitude pulsed voltage to ignite the HID lamp. The proposed transformer structure is characterized by the use of an elongated magnetic core that is made of a magnetic material having a substantially square hysteresis loop and whose saturated flux density is at least two times greater than ferrite, and the primary winding is arranged at the middle section of the elongated magnetic core while the secondary winding is arranged at opposite sides of the primary winding on the elongated magnetic core. This feature allows the transformer of the invention to provide a better voltage transforming effect, and also allows the transformer of the invention to be made more flatted in profile to provide a compact size.
