Abstract
The present invention provides a transformer with high coupling efficiency including a substrate, a bobbin, and a device. The substrate with M sets of pads and M sets of lower conducting wires is defined to have a front surface and a rear surface. Each pad on the substrate is provided as a connecting point for the front surface and the rear surface of the substrate. Each set of pads includes a first pad and a second pad connecting to each other by one corresponding lower conducting wire. The bobbin functioning as a winding reel for the high-voltage conducting wire is provided on the substrate. A device including N sets of upper conducting wires is disposed on the bobbin. Each set of upper conducting wire connect the first pad of one set of pads with the second pad of another set of pads adjacent to the one set of pads to form a low-voltage winding loop on the device and the rear surface of the substrate.
