Abstract
A light weight, bobbinless high voltage transformer and igniter module is provided that meets low-cost and high-reliability requirements for automotive HID products. A printed circuit board () serves as a carrier for low voltage electronic components. A high voltage bar core transformer () is held in a cradle () that accommodates potting material and has a channel () that receives a high voltage wire extending from the transformer for connection with a lead () of an HID lamp (). Thin walls () allow the cradle to serve as the cavity for the potting of the transformer. In addition, multi-layer dielectric material is disposed between the primary and secondary windings. Preferably, the primary winding () is a strap that covers a large surface area of the secondary winding ().
