Energy transfer means for the contactless energy transmission and a process for the contactless energy transmission

摘要

The invention relates to a power transmission device for contactless power transmission, comprising a transmitter unit (36) and a receiver unit (38), wherein the transmitter unit (36) comprises a first transmitter (22) having a first transmission frequency and at least one second transmitter (28) having a second transmission frequency, the second transmission frequency is different from the first transmission frequency, and the first transmitter (22) is galvanically separated from the second transmitter (28), wherein the first transmitter (22) has a first axis of symmetry (126) and the second transmitter (28) has a second axis of symmetry (128), and the first axis of symmetry (126) of the first transmitter (22) and the second axis of symmetry (128) of the second transmitter (28) coincide at least approximately in a transmitter axis of symmetry, and wherein the receiver unit (38) has a first receiver (40) associated with the first transmitter (22) and a second receiver (48) associated with the second transmitter (28).
