  • MRI gradient power system with add on energy buffer
    Patent number: 9897672
    Abstract: The present invention relates to a power supply system (311) for supplying current to a gradient coil (303) of a magnetic resonance imaging system (100), the power supply system (311) comprising: an electrical power supply (309) to supply a first voltage to a gradient amplifier (307) for driving the gradient coil, the gradient amplifier output being connected to the gradient coil (303); an energy buffer having an input connected to the electrical power supply (309), the energy buffer being configured to supply second voltage to the gradient amplifier (307), the energy buffer being in parallel to the gradient amplifier (307) and the electrical power supply (309), the energy buffer comprising a voltage converter (313) configured to control the second voltage as to compensate for a variation in the first voltage resulting from the driving of the gradient coil (303).
