4 Summary

The proposed design was adopted by customers in their project and potential to meet the requirements for exciting the superconductor coil in the MRI system to produce a static magnetic field. The design solves all the challenges that were mentioned aforementioned in this document. In lower cost designs, designers can also scale this design to meet their specific requirements such as update 4-phase to 2-phase and simplify the controller method or algorithm.
