This paper presents a hybrid inductive link for Wireless Power Transfer (WPT) applications. Achieving better power transfer efficiency over a relatively wider distance across coils is the prime objective in most of the WPT systems, but often suffers from power loss in the near field area of inductively coupled coils. One of the reasons for this power loss is the pattern of the magnetic field produced...
This research presents a wireless DC-to-DC power transfer over a short distance. Distance of remotely located target from the source coil and received voltage at the load are the major concern in the Wireless Power Transfer (WPT) applications. The inversely proportional behavior of these parameters degrades the system performance. In order to optimize these values and achieving transfer efficiency,...
This paper presents the new coil design strategy for Wireless Power Transfer (WPT) applications. In order to produce better power transfer efficiency for remotely located load, hybrid approach is proposed using two different coils such as conical and spiral. Hybrid approach refers the coil model by engaging conical as a transmitter and spiral as a receiver in a single system. The field pattern of...
This paper proposes Wireless Power Transfer (WPT) system, consisting of transmitter-receiver coils along with some conditioning and stabilizing circuits. The transmitter circuit is designed with a simple H bridge circuit to supply the pulses to source coil. The efficiency variation or performance with respect to the coil size has been demonstrated in this paper, which is not well demonstrated experimentally...
This work is about modeling a readout system across narrow gaps using inductive means for a contact-less transfer of signal. The signal source could be devices implanted in humans or animals or even devices embedded buried in inaccessible locations for monitoring purposes, while the readout devices are normally in accessible locations in the external world. This work focuses on modeling the coupled...
The advancement of magnetic sensors in biomedical sector has led toward an immense range of applications. Inductive coupling link has been validated as the most suitable and efficient means for wireless transfer of signal where coupling coefficient plays a crucial role to determine the strength of the transmission in power transfer. In view of that an urgent investigation of the relative magnetism...
