Abstract
A gate driver unit is presented. The gate driver unit includes a first power exchanging coil operatively coupled to a power source. The gate driver unit includes a second power exchanging coil configured to receive power from the first power exchanging coil via a magnetic field and a field focusing element disposed between the first power exchanging coil and the second power exchanging coil and configured to focus the magnetic field onto the second power exchanging coil. The gate driver unit also includes a first circuit coupled to the second power exchanging coil. The gate driver unit includes a gate drive subunit operatively coupled to the first circuit and configured to provide an output signal to a control terminal corresponding to a controllable switch of a second circuit. A magnetic resonance imaging system and a method of contactless power transfer in a magnetic resonance imaging system are also presented.
