A Brief Review on Electric Vehicle Dynamic Wireless Power Transfer System: Prospects to Enhance the Coupling Mechanism

In wireless power transmission systems, transmission devices that use energy from a single source transmit energy to spatially receiving devices and generate an electromagnetic field that varies over time, supplying energy to the load. In adjacent magnetic or non-ionizing technologies, electricity is transmitted over short distances using magnetic field, inductive connections between metal electrodes, wires, or capacitors. In this paper, we have applied different coupling mechanism for frequency operation such as inductive, capacitive, magnetic which comes under non- radiative and microwaves and lasers (radiative). Finally, we evaluate the performance parameters of coupling mechanism with different performance metrics such as power, efficiency, frequency, induced voltage, coupling coefficient, air-gap and velocity.
