Resonant coupling is the technology widely applied for efficient wireless power transfer in medium ranges. This paper applies reflected load theory to analyze the multi-coil system consisting of several resonators. Different number of resonators would change resistance reflected to primary side and influence power delivered to load. To optimize power transmission of system, this paper purposes a method...
This paper proposed an approach to extend the transmission distances of wireless power transmission (WPT) systems under the constraint of the coil size and optimized delivered power and efficiency. Based on the reflected load theory, the inductive coupling coils can be modelled as an equivalent circuit for simple analysis and be extended to multiple-coil wireless power transmission systems. According...
A novel rectenna is proposed for the power supply of implantable dental devices in biomedical monitor applications. Several challenges include the design of compact implantable antenna on teeth and the conversion efficiency of the rectifier at low input power for biomedical applications, so a high efficient dental rectenna is required. In this paper, a compact dental antenna is designed within 8×11...
