ENHANCEMENT OF CONTACTLESS BATTERY CHARGER USING PLANAR PCB WINDINGS

Abstract

This project was creating to charge the battery by using the principles of Contactless Energy Transfer (CET) in transferring energy. It is form by the inverter and the rectifier circuit. The inverter is known as a device that converts direct current (DC) power to alternating current (AC) . In this case the inverter is the primary side or desk-top unit. While, the rectifiers functioning to convert the AC voltage into DC or low-frequency AC to supply loads. The rectifiers function as the secondary side. But for this project, the planar PCB windings is fit also to the circuit to connect both circuit and functioning as the contactless energy transfer device by creating a magnetic field and minimize the leakage inductance to produce good coupling coefficient.
