Patent ID: 6930483

Claim:
A gradient coil system, comprising: a capacitor having a first side and a second side; at least one gradient coil comprising a first end and a second end; a first inductor connected to a first output end of a switched amplifier and connected to the first end of the gradient coil thereby providing a switched amplified current from the switched amplifier to the gradient coil; a second inductor connected to the first end of the gradient coil thereby providing a second current to the gradient coil, wherein the second current is substantially out of phase with the switched amplified current; and a transformer electrically coupling the first inductor with the second inductor, the transformer further comprising: a primary side and a secondary side, wherein the primary side of the transformer is connected across the first inductor and wherein the first side of the capacitor is connected to a second side of the secondary side of the transformer and the second side of the capacitor is connected to a second output end of the switched amplifier.
