Research on Wireless Power transmission system between satellites

The Wireless Power Transfer (WPT) technology is a promising way to break the limit of capability and operation for satellites and make the satellites much lighter, smaller and more flexible and durable. This paper introduces the system integration techniques of WPT between satellites including the energy control subsystem, the laser-WPT subsystem and the microwave-WPT subsystem, and discusses the mechanisms of laser WPT subsystem and the ground demonstration platform of the microwave-WPT subsystem. Finally, this paper gives the experimental results of the WPT on the ground.
