Abstract: A switched mode power supply (SMPS) employs only energy storage components that are devoid of ferromagnetic materials. The SMPS operates only at switching frequencies such that any potential electromagnetic interference of interest is generated at frequencies appearing only outside the imaging bandwidth of a corresponding magnetic resonance imaging system powered by the SMPS.

Abstract: Embodiments of the present disclosure include a magnetic resonant imaging (MRI) system including a gradient driver configured to deliver a pulse sequence to gradient coils in the MRI system. The gradient driver may be interleaved, and may include two or more interleaved drivers, such that a high amplitude pulse may be output by operating the two interleaved parts of the gradient driver while spreading the electrical loss and maintaining the thermal stability of the system. In one embodiment, each interleaved driver may be rated to output approximately half a maximum amplitude of a current utilized by the gradient coil, and only one interleaved driver may be in operation if only one interleaved driver is sufficient for delivering a necessary pulse to the coils. Further, the interleaved drivers may alternate in operation to maintain thermal stability in the switching semiconductors of the gradient driver.
