Abstract
The invention relates to a multi-coil wireless power apparatus (100) comprising a first wireless power circuit (121) connectable to a first resonant tank (101, 21), wherein the first resonant tank (101, 21) is arranged to transfer inductive energy at a first frequency, and a second wireless power circuit (122) connectable to a second resonant tank (102, 22), wherein the second resonant tank (102, 22) is arranged to transfer inductive energy at a second frequency. The first resonant tank (101,21) is tunable to the second frequency when the second inductive energy coil (106, 26, 32, 42, 52) is active. The invention further relates to an apparatus and a computer program product.
