Abstract
A coil control device of a magnetic resonance imaging system includes a DC-DC switching converter and a controller. The DC-DC switching converter is configured for switching and converting a DC power supply to a DC current or a DC voltage. An input end of the DC-DC switching converter is connected in parallel to the DC power supply. The controller is configured to control the DC-DC switching converter to switch and provide the DC current or the DC voltage. In some embodiments of the coil control device described herein, two power supplies (e.g., +15 V and −32 V) may be reduced to one power supply (e.g., +15 V), thereby saving energy and foregoing a water-cooling system.
