ABSTRACT:
The present invention is an efficient method of transferring energy wirelessly and an apparatus which efficiently transfers energy wirelessly. A high transmission frequency is modulated by a lower frequency in order to reduce the intensity of the resulting electromagnetic interference. The present invention creates a high magnetic flux density by employing a large number of small induction coils which generates a strong electromagnetic field in a wide range of directions. The present invention is a “true wireless system” in that it overcomes the range limitations and requirement for precise alignment present in the field of art. A number of apparatuses and practical implementations for contactless energy transfer exist.
