Wireless Power for Autonomous Sensor Systems
Main challenges for tomorrow's WPT technologies
Description of the magnetodynamic WPT technology.
Two operating modes of magnetodynamic WPT are considered: the continuously rotating mode offering a high power density solution, and the resonant mode enabling mid-range power transfer:
These two modes differ also on some other practical aspects. For example, the continuous mode has more degrees of freedom in orientation, a larger bandwidth and its design is more compact. However, in this mode, the transmitter current has to ramp up from a low frequency to the operation frequency in order to start.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
