- Abstract:
- As the technology is moving towards the world of wireless systems, the concept of inductive power transfer between galvanically isolated coils is becoming significant for low power application. The main advantages are its minimum influence of external atmospheric factors, smooth supply of power to moving systems, least maintenance and ruggedness. In general, the system should be designed in such a way that the received power at the load should not be less than the minimum required power up to a certain distance between coils. This paper proposes the implementation of two different power enhancement techniques for increasing the received power at the load in a two coaxial coil system which is powered by a source having some significant impedance. For these two techniques, analytical model is built and it is followed by simulation and verification by experiment. The first model gives freedom to the user to use it in his own way without changing the design of the circuit; and the second one lets the user design the circuit to obtain more power. By using these two methods; the power as well as the flexibility of the system increase, thereby facilitating the use of inductive power transfer devices.
