Against the rapid growth of the energy internet, electric transportation, and intelligent equipment, magnetically coupled wireless power transfer (MC-WPT) has become a key solution for medium- and short-range high-power wireless energy delivery, owing to its non-radiative transmission, intrinsic electromagnetic safety, and strong environmental adaptability. This paper presents a mechanism-oriented and systematic review of the theoretical foundations and technological evolution of MC-WPT, focusing on magnetic coupling structure optimization and mutual inductance modeling, compensation topologies and their parameter sensitivity, coordinated design of power electronics and control, dynamic wireless power transfer mechanisms, and electromagnetic compatibility and safety constraints. Representative solutions are comparatively analyzed in terms of performance limits, applicable scenarios, and inherent trade-offs, revealing the coupled and synergistic roles of structure, circuit parameters, and control strategies. Key challenges for large-scale and standardized deployment—including interoperability, operational stability under complex conditions, and incomplete safety and standardization frameworks—are further identified, and future trends toward advanced magnetic materials, intelligent control, and deep integration with power grids and transportation systems are discussed. This review provides a unified conceptual framework to support theoretical research, engineering design, and standard development for MC-WPT technologies.
