Special Issue Information

Dear Colleagues,

Inductive power transfer (IPT) has attracted more and more attention due to the rapid development of power electronics, electric vehicles (EVs), consumer electronics, and robots. Since IPT technology enjoys the merits of convenience, low maintenance, reliability, safety, automation, and electrical isolation, more and more academic researchers and industries are becoming involved in the wireless charging area. Thus, the IPT shows significant meanings for charging portable electronic devices, automatic robots, integrated circuits, distributed sensors, electric vehicles, etc. This Special Issue aims to provide a timely opportunity for academic researchers and industrial engineers to present, discuss, and exchange the latest results and findings of IPT technologies on semiconductor technologies, power electronic topologies, compensation network design, electromagnetic field theory, wireless sensors, as well as the future development of high-power applications.

Topics of interest include but are not limited to:

  • Wireless sensor networks;
  • Distributed wireless power transfer;
  • Optimized switching techniques for high power IPT;
  • Wireless charging systems for robots and smart home appliances;
  • Electromagnetic compatibility and safety designs;
  • New materials and topologies for magnetic core;
  • Multiple-frequency multiple-objective IPT applications;
  • Novel SiC and GaN converters for IPT;
  • Wireless charging for electric vehicles;
  • Emerging applications such as wireless motor, lighting, heating, etc.;
  • Review papers on IPT techniques and development.

This paper proposes an extreme learning machine (ELM)-based adaptive sliding mode control strategy for the receiver-side buck converter system in the wireless power transfer system subjecting to the lumped uncertainty. The proposed control strategy utilizes a singularity-free fixed-time sliding mode (FTSM) feedback control, which ensures a fixed-time convergence for both the sliding variable and voltage tracking error. An ELM-based uncertainty bound estimator is further designed to learn the uncertainty bound information in real-time, which opportunely loosens the constraint of bound information requirement for sliding mode control design. The global stability of the closed-loop system is rigidly analyzed, and the good performance of the proposed control strategy is validated by comparison experiments which exhibit ideal overshoot elimination, 45.70–51.72% reduction of settling time, and 13.65–36.96% reduction of the root mean square value for voltage tracking error with respect to different load types.

An inductively powered passive transmitter architecture for wireless sensornodes is presented in this paper. The intended applications are inductively powered internally illuminated photoreactors. The application range of photoreactors is wide. They are used, e.g., for microalgae cultivation or for photochemistry, just to name two important fields of use. The inductive powering system used to transmit energy to the wireless internal illumination system is to be additionally used to supply the here presented transmitter. The aim of expanding the named internal illuminated photoreactors with wireless sensors is to obtain a better insight into the processes inside it. This will be achieved by measuring essential parameters such as, e.g., the temperature, pH value, or gas concentrations of the medium inside the reactor, which for algal cultivation would be water. Due to the passive architecture of the transmitter electronics, there is no need for batteries, and therefore, no temporal limitations in their operational cycle are given. The data transmission is also implemented using the inductive layer in the low frequency range. The data transmitting coil and the energy receive coil are implemented as one and the same coil in order to avoid interference and unwanted couplings between them, and in order to save weight and space. Additionally, the transmitter works in a two-step alternating cycle: the energy harvesting step, followed by the data transmission step. The measured values are sent using on-off keying. Therefore, a Colpitts oscillator is switched on and off. The circuit is simulated using SPICE simulations and consequentially implemented as a prototype in order to perform practical analyses and measurements. The feasibility of our transmitter is therefore shown with the performed circuit simulations, and practically, by testing our prototype on an internal illuminated laboratory scaled photoreactor.
