Abstract

We studied on effective quench protection method to prevent damage from unexpected quench of the inductively coupled superconducting magnet systems for magnetic resonance imaging. And we suggested quench protection circuit that is combined with several protection techniques. This circuit has the capacity to maintain the symmetric nature of the magnetic field and the active shielding effect and to protect shim coils during a quench.
