摘要： A balanced transformer having an auxiliary coil has a bobbin, a balanced coil set, a detective coil, and an iron core set. The balanced coil set and the detective coil is wound onto the bobbin. The iron core set penetrates through the bobbin. The balanced transformer can be used in a driving circuit of a backlight module of an LCD device. The balanced coil set is electrically connected to CCFLs of the backlight module. The detective coil is electrically connected to a protection circuit of the backlight module. When currents respectively passing through the CCFLs are not equal to each other, two ends of the detective coil induct a voltage to form a protection feedback signal transmitted to the protection circuit. Therefore, the balanced transformer is capable of detecting an unusual current, so as to further protect the balanced transformer and the driving circuit of the backlight module.

摘要： A modified transformer structure has two U-shaped magnetic cores, a low-voltage side coil, a high-voltage side coil, and a C-shaped magnetic core. The two U-shaped magnetic cores and the C-shaped magnetic core are assembled with the low-voltage side coil and the high-voltage side coil, respectively. Through the C-shaped magnetic core, when a short circuit occurs in the high-voltage side coil of the transformer, power conversion of the low-voltage side coil is not affected, hence accomplishing short-circuit protection of the transformer. Moreover, the counter magnetomotive force generated at the low-voltage side coil of the transformer can be reduced through the C-shaped magnetic core, hence protecting the low-voltage side coil and also decreasing heat generated by the transformer.

摘要： The invention describes a multiple lamp balance transformer and a drive circuit. The multiple lamp balance transformer has two magnetic cores with a closed magnetic flux path and two coils wound around the closed magnetic flux path. The two coils have the same number of windings. The impedance property of the coil and Lenz's Law are used to balance the operating current of the lamps connected to the coils. The drive circuit has a multiple lamp balance transformer connected to several lamps, and a boost transformer uses a controller to supply the current and voltage to the lamps. A current detect/protect circuit connected to the coils and the controller detects the current passing through the coils and converts the operating current of the lamp into a voltage to be sent to the controller, so that the controller controls and provides sufficient power to the lamps.
