The power transfer system is a polyphase system that creates a travelling magnetic field in the air or liquid gap, implementing a resonant electro-magnetic (EM) field to allow larger gap separations and less precise alignments. The power transfer system may have a polyphase dynamoelectric machine attached to primary mechanical-inertial storage device with multiple stator and rotor ports connected to a polyphase traveling-wave inductive power transmitter apparatus. The system may be of use in transferring power to underwater vehicles in a subsea salt water environment. Such a power transfer system may part of a larger system for underwater power transfer, for instance at depths of at least 10 km, and/or at distances of 1 to 50 km."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Polyphase contactless induction power transfer system for transferring electrical power across gap","description":"An inductive power transfer system is used for transferring electrical power across a gap, such as an air gap or a liquid gap, such as to unmanned autonomous vehicles (UAVs).
