Special Issue Information

Dear Colleagues,

The concept of wireless power transfer can be traced back to Tesla’s experimentation in 1899 and has experienced renewed momentum since the introduction of resonant coupling wireless power transfer technology in 2007. So far, some commercial products based on near-field wireless power transfer have been successfully rolled out. Far-field wireless power harvesting has been considered a promising and key enabling technology for energizing a large-scale sensing and communication network.     

Challenges in wireless power transfer and harvesting attract plots of research efforts, such as enhancing operating distance (near-field), improving rectifying efficiency (far-field), optimizing system-level integrated design, and identifying emerging applications. This Special Issue aims to invite submissions related to wireless power transfer and harvesting technology that highlight recent advancements and provide a forward-looking perspective.  

Topics of interest include but are not limited to:

  1. Inductive wireless power transfer;
  2. Capacitive wireless power transfer;
  3. Static and dynamic wireless charging;
  4. Acoustic, optical, and solar wireless power transfer;
  5. High-frequency rectifying circuit design;
  6. Rectennas and antenna design for rectifiers;
  7. Simultaneous wireless information and power transfer;
  8. Hybrid power harvesters;
  9. Battery-free sensing and communications systems;
  10. Backscattering, RFID, and electronic tags.

In this paper was analysed a wireless power transfer system (WPT) with multiple resonators supplying, for example, sensors or LED lighting. Energy is transferred simultaneously using a group of identical planar spiral circular coils acting as transmitters and receivers. These coils were arranged to form transmitting and receiving planes. The receivers were connected to independent power supply circuits of each, e.g., sensor or LED lighting. Higher power reliability and flexibility can be achieved by isolating these circuits. The proposed system was described and discussed. Taking into account the skin effect and mutual couplings, a theoretical analysis was made. A detailed analysis was made at the resonant frequency of the system. The system was modeled using a matrix equation and appropriate formulas. The calculations were verified experimentally for different loads and two distances between transmitters and receivers. The efficiency and receiver power were compared and discussed. The maximum efficiency was about 45% at the small distance between the planes. The maximum efficiency of the WPT system decreased more than two times to less than 20% when the distance between the coils was doubled. The results and discussion of the conducted analysis may provide valuable knowledge when designing this type of system. Full article
