Objective: The main theme of this paper is to eliminate the frequency split in short range Wireless Power Transfer (WPT) system by magnetic resonance coupling. Analysis: The common basic two coils based magnetic resonance WPT system is taken for the analysis; the frequency and transfer coefficient are plotted for different dimensions of the coil. Using genetic algorithm, the lumped impedance parameters are determined, which is used for the tuning of the active matching circuit. Based on the experimental results it has been observed that the frequency split can be eliminated by tuning the matching circuit properly for the corresponding distance and higher efficiency can be achieved for short range. Findings: The frequency split elimination techniques can be used in dynamic transmitter and receiver wireless charging system. Application: This system can be employed in short range wireless power transfer such as neural implants, capsule robots, micro-robots and electric vehicle charging and so on.Keywords

Objective: The main theme of this paper is to analyze the wireless power transfer system efficiency in real time with different medium, distance and angle between the source and load coil. Analysis: The transmitter side of Wireless Power Transfer (WPT) system connected to the supply and receiver side is connected with load. The analysis is carried out for 2, 3 and 4 coil system in experimental test setup. Based on the experimental results it has been observed that the 4 coil WPT system gives better performance as compared with other two. Also it shows higher efficiency, if the angle of orientation of the load coil is small with the source coil.Findings: The four coil WPT system can be used in low power wireless charging devices with the distance of 3 to 15c.m between transmitter and receiver. Application: This system can be employed in electric vehicle charging, Bio implants, microrobots and so on.Keywords
