Abstract
A wireless power transmitter for powering a remote receiver using a laser beam, the laser beam generator having current inputs and outputs electrically insulated from their surroundings, and each including a separate controlled gated switch. The transmitter has a beam adjustment element for switching the beam between a collimated beam for power transfer, and a more divergent beam for scanning, which is performed by a beam deflector. A detection system detect the presence of a receiver, and is used to ensure accurate beam impingement on the power receiving element. A controller senses when the beam is centered on the power receiving element, switches from the divergent scanning beam to the collimated beam, and instructs the beam generator to raise the power of the laser beam to a level for powering the receiver. The gate controller operates at a higher voltage than the other system control circuits.
