Special Issue Information

Dear Colleagues,

Wireless power transfer (WPT) has rapidly advanced over the past decade and continues to do so. Under the attention of more and more researchers, this technology has shown broad application prospects in different fields from milliwatts to megawatts and from near-field to far-field, such as sensors, medical implants, consumer electronics, household appliances, electric vehicles, aerospace, ocean exploration, railway applications, etc. With the advancement in power semiconductor devices, magnetic materials, topologies, coupling interfaces and control strategies, WPT technology has made continuous breakthroughs in transmission power, efficiency, distance, and system anti-interference and integration, etc. This Special Issue, entitled “Advanced Technologies and Applications in Wireless Power Transfer Systems”, focuses on the recent theoretical and applied research achievements of WPT, including, but not limited to, system sub-modules such as power converters, compensation networks, coupling interfaces, controllers, etc., as well as auxiliary functions such as power/signal parallel transmission, foreign-object detection, position monitoring, etc. In addition, articles which discuss the application of WPT technology would also be of particular interest.

We invite original manuscripts presenting recent advances in this area including, but not limited to, the following topics:

  • Wireless power transfer for land transportation (E-bikes, electric vehicles, rail transit, etc.);
  • Wireless power transfer for underwater vehicles;
  • Wireless power transfer for aircraft (unmanned aerial vehicles, aerospace, etc.);
  • Wireless power transfer for household appliances;
  • Wireless power transfer for consumer electronics;
  • Wireless power transfer for biomedical implant devices;
  • Wireless power transfer for Internet of Things (IoTs) and sensors;
  • Advanced converter, compensation, coupler and controller for wireless power transfer;
  • Capacitive power transfer;
  • Ultrasonic power transfer;
  • Energy harvesting;
  • Power and signal parallel transmission for wireless power transfer;
  • Foreign object detection for wireless power transfer;
  • Position monitoring for wireless power transfer.

In order to solve the misalignment problem of wireless power transmission, this paper designed and analyzed the omnidirectional receiver with multi-coil. The circuit models and transmission characteristics of the wireless power transfer system (WPTS) containing multi-coil were established. Besides, an accurate mutual inductance modelling method of the circular coil under different horizontal offset and angular deflection was presented. Based on the circuit models and the mutual inductance model, the relationship between transmission characteristics and the coil parameters were studied. Simultaneously, the design method which can synthetically and quantificationally consider the radius of the coil and the number of turns was proposed. Finally, an omnidirectional receiver with multi-coil using the quantificational model and transmission characteristics in different horizontal offset and angular deflection was designed.The transmission efficiency of three-coils-receiver system was up 12.3% higher than that of one-coil-receiver system and 4% higher than that of two-coils-receiver system when horizontal offset was between 0 cm and 30 cm. Similarly, when angular deflection was between 0 and π/2, the efficiency of three-coils-receiver system was up 73.25% higher than that of one-coil-receiver system and 1.6% higher than that of two-coils-receiver system.
