A compact wireless power transfer (WPT) system being used to power wireless patient coils would require a compact power amplifier that can operate inside the MRI bore. A Class-EF power amplifier is designed and implemented that uses air-core inductors and is capable of driving the coupled resonant coils used for WPT with similar efficiency to a system that uses a large and expensive power amplifier that is outside the scan room. This new power amplifier is very compact and is also very cost-effective.
