FLYBACK TRANSFORMER DEVICE

摘要

The flyback transformer comprising a core (1) and a winding (2) is fixed on a PCB (9). The PCB includes a pair of holes (8) for inserting the ground wire. The holes are apart as much as 5 mm from the core and winding respectively. Then the magnetic field generated at the core is shielded by the closed loop of the lead wires and the iron or copper plates.
