Abstract
Disclosed herein are methods and systems for providing a ballast load for a magnetic resonance power source. One embodiment takes the form of a magnetic resonance power source that includes a source coil, a load-detection module, a tunable ballast coil circuit, and a controller programmed to carry out a set of functions. The set of functions includes obtaining, via the load-detection module, an estimated load on the source coil. The set of functions also includes decreasing the power received by the tunable ballast coil circuit from the source coil when the estimated load on the source coil is greater than a desired load on the source coil. The set of functions also includes increasing the power received by the tunable ballast coil circuit from the source coil when the estimated load on the source coil is less than the desired load on the source coil.
