Wireless Charger Transmitter Schematic

A circuit to manage the charging process for li ion or nimh battery chemistries.

Wireless charger transmitter schematic. The first circuit is transmitter circuit used to produce voltage wirelessly. Tightly coupled wireless charging technology uses magnetic induction to transfer power from a transmitter tx to a receiver rx. Semtech s exhilarating portfolio of wireless charging products has transformed connectivity as we know it. Wireless gadgets charger circuit.

This circuit constructed to produce high frequency magnetic flux. You can use copper or aluminium wire but copper is a good conducting material its giver better efficiency. The transmitter circuit of wireless mobile charger circuit diagram is shown in figure 1 and is built around timer ic 555 a general purpose npn transistor bc547 n channel mosfet irf540n lc tuned circuit and a 5 volt series voltage regulator 7805. The transmitter circuit for this wireless cellphone charger is the crucial stage and must be built accurately and it must be structured as per the popular tesla s pancake coil arrangement as shown below.

The field is captured by a coil on the rx side. Transmitter circuit for wireless mobile charger circuit diagram. Inductive charger schematic with test points.

The schematic shown in figure 1 is an example system with test points for troubleshooting possible problems plus the meter placement that is necessary to calculate power efficiency. The center tapped coil is made through 20 swg enameled copper wire 6 cm dia and 5 turns with center tap in middle. The transmitter circuit consists of dc source oscillator circuit and a transmitter coil. The field works through air no magnetic circuit links the coils.

Our out of the box ready infrastructure can be used in essentially any environment providing wireless charging capabilities for standards compliant mobile phones and tablets.
