ADJUSTABLE WIRELESS CHARGER

摘要

PURPOSE: A wireless charger is provided to reduce standby consumption power by reducing internal resistance in a coil. CONSTITUTION: A wireless charger arranges a coil and a condenser in parallel for resonance with a first coil. The wireless charger is resonated in a standby state. The first coil consists of a PCB(Printed Circuit Board) and forms pattern thickness as 74um-200um. 30Vrms-250Vrms of voltages is applied to the first coil. A plurality of first coils is grouped for forming a frequency generator(63) and an oscillator(62). A second coil is approached to a battery by passing through a DC(Direct Current) rectifier(10a) and a charger circuit(12).
