| Wireless (contactless) transfer of electric power is a disruptive technology because it abandons wired transmission technology, the only technology used in electrical and electronic engineering until recently, just like in the past animal traction and film photography were replaced by mechanical traction and digital photography. Although revealed at the end of the nineteenth century through Tesla’s inventions, it could be applied in practice only in the ‘80s of the twentieth century, with the development of power electronics and microprocessors. After an introduction and an overview of the operating principles, the paper presents the readiness level reached by this technology, the stage of standardization, Romanian achievements and future prospects for high power applications. |
