Design of Wireless Power Transfer System for Charging of Electronic Gadgets

Wireless charging of gadgets is one of the new emerging technologies in the world at present moment. The most common method used is wireless power transfer is by using the method of inductive coupling. Wireless power transfer is one of the simplest and inexpensive ways of charging as it eliminates the use of conventional copper cables and current carrying wires. The inductive coupling technique is used since currently it is the easiest method of wireless power transfer because of high efficiency and large amount of the energy transferred. Its versatility and range of applications the power transferred will be used to charge a battery with the aid of additional circuitry. This research work focuses on the study of wireless power transfer for the purpose of transferring energy at maximum efficiency within a small range or in the near field region. The motivation to this proposed design model is contact less mobile device charging about 5cm-100cm distance range, which can be used to charge the mobile electronic devices like mobile phones, laptops, smart phones wirelessly. This proposed design is very helpful in the pandemic situation to charge electronic gadgets contactless as well wirelessly in the hospitals, public transports like metro stations, educational institutions, and in office communication systems.
