Patent ID: 8760164

Claim:
A magnetic resonance imaging (MRI) system comprising: a gradient coil disposed cylindrically around a scanning volume; and two or more interleaved gradient drivers coupled in parallel with one another and coupled to the gradient coil through a transformer, wherein each of the two or more interleaved gradient drivers is configured to deliver less than a maximum amplitude of a current utilized by the gradient coil and wherein each interleaved gradient driver, of the two or more interleaved gradient drivers, itself comprises: at least two levels of driver components coupled in series with one another, wherein each level of the at least two levels of driver components comprises a voltage source; and a terminal coupled to the transformer; and wherein the parallel coupling between the two or more interleaved gradient drivers is such that the respective at least two levels of driver components of each interleaved gradient driver are coupled in parallel with the respective at least two levels of driver components of all other interleaved gradient drivers of the two or more interleaved gradient drivers.
