Özet
This research focuses on designing and constructing a wireless charger for mobile phones. The
wireless charging technique used is the inductive technique, which involves designing and
constructing a power supply unit, an oscillator circuit, the transmitter and receiver coils, and
rectification and filtering circuits. The oscillator circuit converts the 9 V DC voltage from the
power supply unit to an oscillating magnetic field of high frequency (about 200 kHz) on the
transmitter coil. This time-varying magnetic field induces EMF on the receiver coil according to
the principles of mutual inductance. The induced voltage on the receiver coil is then passed through
the required circuits for rectification, filtering, and regulation. The output of the receiver unit is
used to charge a mobile phone. ATMEGA328P microcontroller is also embedded in the wireless
charger to detect and display the working state of the wireless charger through the 16 x 2 LCD to
make the device more user-friendly and easier to use. Based on the design, the wireless charger
can produce up to 5 V voltage and 450 mA current at the output of the receiver circuit, which are
the minimum requirements for charging a mobile phone. Also, the wireless charger can charge a
mobile phone effectively at a distance of 6 cm. The embedded microcontroller unit also enhances
the interaction between the wireless charger and the users.
