 In this technically advanced era, technology isthe cornerstoneof civilization.The importance of technology bringsintofocus the value ofchargingtechnologies. The scope of the industry is moving towards Wireless Charging as this allows for easier charging without the use of wires and is extremely convenient. Wireless chargers that exist currently are inductively coupled. Inductive coupling tends to cause electromagnetic disruption in most of the devices that is sensitive to electromagnetic interference. This design which is based on capacitive coupling overcomes the disadvantage of any interference with other devices as it is based on Electrostatic Coupling. Thisdesign is able to charge a low device through contactless charging efficiently. The designed wireless charger unit was simulated in Proteus8 Professional Suite. A transformer is used to step down the supply voltage to the requisite value. The H-Bridge circuit is used to convert dc to a con the Transmitter side and the Rectifier circuit is used to convert ac back to dc in theReceiver side of the device. An LED which is a low powered device is connected to the receiver side of the circuit as a load. Power is transferred to the circuit via the plates which are separated by a dielectric medium. A wireless charger was built, however, the size and the weight are two very important criteria in the design of any charger and these factors are affected by the effective plate size of the coupling capacitors and must be taken into consideration for the design of a charger.
