    Abstract:

    Omnidirectional wireless power transfer technology is widely concerned by domestic and foreign research institutions and research institutes due to its unique advantages such as good location robustness, high safety and reliability, and strong environmental affinity. Firstly, the application field of omnidirectional wireless power transfer technology and the domestic and foreign development are described. Then, key fundamental problems of the electromagnetic coupling system are analyzed in detail, including the design and optimization of electromagnetic coupling structure, magnetic field direction control strategy and electromagnetic compatibility. Finally, key problems and technical difficulties in engineering, productization and commercialization of the technology are discussed, and its application prospect is further prospected.
