An Efficient Class-d Dc-dc Converter for Wireless Power Transfer Technology

The research progress in the field of Wireless Power Transmission (WPT) using Magnetic Resonance coupling with DC-DC converter. The transfer of energy from a source to a receiver has traditionally necessitated the use of a physical connection, but wireless power transfer (WPT) is essentially the transmission of an electrical current from a power source to a receiving device without the need for a physical connection. Wireless power transfer is based on the principle of magnetic resonance. The process whereby electricity is transfer between two objects through coils. The important feature of WPT is high efficiency at large transmission distance. To make the technique of WPT feasible for industrial and commercial applications. WPT is an extremely useful technology that has numerous applications and benefits such as cell phones, laptops and other mobile devices could function without ever having to be plugged in. The simulation results are carried out using MATLAB Simulink environment.
