Zusammenfassung:	Power systems and circuitry for generation of gradient magnetic fields in magnetic resonance imaging MRI systems 10 are discussed herein. Embodiments may include the use of multiple gradient amplifiers 106 that share a high-frequency power distribution unit 104, 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 107. The gradient amplifiers may make use of modern semiconductor materials that provide high-frequency, high voltage performance, and maybe implemented using single semiconductor bridges 350.
