The present invention is suitable for voltage transformation and regulation.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a loose coupling transformer. Background technique [0002] When wired power transmission supplies power to multiple devices, there are problems of messy winding and unsightly appearance; when powering underground equipment, electric sparks between contacts are likely to cause dust explosion accidents; when powering underwater equipment, electric leakage accidents are likely to occur; When powering implanted medical equipment, there are problems such as susceptibility to infection and inconvenience; when slip ring power transmission is powering rotating equipment, there are problems such as large mechanical wear and short life. The above shortcomings limit the application of contact power supply in these fields. [0003] Wireless Power Transfer (WPT) technology completes energy transmission through different media such as space magnetic fields, sp...
