Abstract
A framework for power management. The framework includes at least one power distribution board disposed within a radio-frequency (RF) cabin of a medical imaging system and coupled to an external reference clock. The power distribution board may include a clock circuit that generates one or more output clock signals based on a reference clock signal from the external reference clock. One or more switching regulators may be coupled to the clock circuit. The one or more switching regulators may be synchronized to the one or more output clock signals and provide power to one or more endpoint loads.
Claims20
A power management system, comprising:
- at least one power distribution board disposed within a radio-frequency (RF) cabin of a medical imaging system, wherein the power distribution board is directly coupled to an external reference clock and a single power supply outside the RF cabin, and includes
- a clock circuit that generates one or more output clock signals based on a reference clock signal from the external reference clock, and
- one or more switching regulators coupled to the clock circuit, wherein the one or more switching regulators are synchronized to the one or more output clock signals, wherein the one or more switching regulators provide power from the single power supply to one or more endpoint loads.
A power management system, comprising:
- first and second power distribution boards disposed within a radio-frequency (RF) cabin of a medical imaging system, wherein the first and second power distribution boards are directly coupled to an external reference clock and a single power supply outside the RF cabin, wherein each of the first and second power distribution boards includes
- a clock circuit that generates one or more output clock signals based on a reference clock signal from the external reference clock, and
- one or more switching regulators coupled to the clock circuit, wherein the one or more switching regulators are synchronized to the one or more output clock signals, wherein the one or more switching regulators provide power from the single power supply to one or more endpoint loads.
A method of power management, comprising:
- providing a power distribution board within a radio-frequency (RF) cabin of a medical imaging system, wherein the power distribution board includes a clock circuit and one or more switching regulators, wherein the power distribution board is directly coupled to a single power supply outside the RF cabin;
- generating, by the clock circuit, one or more output clock signals based on a reference clock signal;
- synchronizing the one or more switching regulators to the one or more output clock signals;
- and
- converting, by the one or more switching regulators, power from a single power supply outside the RF cabin to multiple power rails inside the RF cabin for one or more endpoint loads.
