Special Session 3
Primary-Side Control Technologies for Wireless Power Transfer Systems
This Special Session focuses on recent advances
and emerging trends in primary-side control for wireless power
transfer (WPT) systems. With the rapid development of WPT
technologies in applications such as consumer electronics, medical
implants, electric vehicles, drones, and underwater systems, there
is an increasing demand for control methods that can simultaneously
achieve high efficiency, strong robustness, compact receiver design,
and reliable operation. Recent industrial developments, including
the evolution of the Qi2 standard, further emphasize the importance
of achieving both compatibility and optimal charging performance in
next-generation WPT systems.
Primary-side control has attracted significant attention as a
promising solution to these challenges. By transferring most control
functions to the transmitter side, primary-side control can simplify
receiver circuits, reduce system cost and power consumption,
eliminate extensive wireless communication requirements, and improve
system robustness against electromagnetic interference. These
advantages make it particularly suitable for applications where
receiver size, reliability, and operational stability are critical.
The scope of this Special Session includes, but is not limited to,
primary-side control strategies, communication-free control methods,
efficiency optimization, receiver simplification, foreign object
detection, dynamic wireless charging, high-power WPT systems,
compact receiver applications, and emerging industrial and
biomedical applications. The session aims to provide an
interdisciplinary platform for researchers and engineers to exchange
innovative ideas and discuss future directions in advanced WPT
control technologies.
