Coreless superthin PCB transformer and non-contact battery charger using the same |
摘要 |
A super-thin PCB (Printed Circuit Board) transformer is manufactured by installing windings on a common PCB without using a magnetic core. A non-contact battery charger using the PCB transformer includes a converter for converting a supply voltage into a high frequency square wave and then applying the converted square wave into a first winding of the PCB transformer; and a charger for converting an electromotive force to a DC voltage to apply the converted DC voltage to a charge circuit, the electromotive force being induced to a second winding of the PCB transformer by a magnetic wave which is generated by the square wave induced in the first winding of the PCB transformer. The non-contact battery charger can be applied to portable information communication and calculation devices such as a mobile telephone, a PDA (Personal Digital Assistant Device), a palm-top, an interetphone, etc.
