Abstract
The present application provides a switching power supply and a magnetic resonance imaging system. The switching power supply is used for supplying power to a radio frequency coil control device, wherein the radio frequency coil control device is used for controlling a flow direction of radio frequency power output by a radio frequency amplifier of the magnetic resonance imaging system. Moreover, the switching power supply comprises a first power unit, a second power unit, and an air-cored transformer, the second power unit and the first power unit being electrically coupled through the air-cored transformer, wherein the switching power supply is configured to operate at a preset frequency, and frequency multiplication of the preset frequency is beyond a reception bandwidth of the magnetic resonance imaging system.
