Abstract
Systems and methods are provided for wireless transmission of power or information. A supplying system include a signal source and a transmitter unit. A consuming system includes an electrical load and a receiver unit. Electrical power or information are transmitted wirelessly from the supplying system to the consuming system. The transmitter unit can include a step up transformer. The receiver unit can include a step down transformer. The transmitter unit and receiver unit are not connected to a common ground, resulting in a truly wireless system for transmitting power or information.
