Abstract:
Power systems and circuitry for generation of gradient magnetic fields in magnetic resonance imaging (MRI) systems are discussed herein. Embodiments may include the use of multiple gradient amplifiers that share a high-frequency power distribution unit, that may perform power distribution and power supply roles. The high-frequency power distribution unit may allow the use of a single power supply to drive multiple gradient amplifiers via a shared power bus. The gradient amplifiers may make use of modern semiconductor materials that provide high-frequency, high voltage performance, and may be implemented using single semiconductor bridges.

Claim (Index 18):
A gradient amplifier configured to drive a gradient coil of a magnetic resonance imaging (MRI) system, comprising:\n a first branch of a single semiconductor bridge comprising a first switch and a second switch; a first terminal coupled to a midpoint of the first branch; a second branch of the single semiconductor bridge comprising a third switch and a fourth switch; and a second terminal coupled to a midpoint of the second branch; wherein the first branch and the second branch are arranged in parallel with respect to an input DC bus and wherein the first terminal and the second terminal are configured to provide an output the gradient coil.
