Magnetic resonance power supply apparatus

A magnetic resonance power supply apparatus comprising:

• a communication circuit configured to receive, from a highest-priority power receiving device having a highest power supply priority level from among a plurality of power receiving devices inside a power supply availability zone, information enabling computation of a power supply efficiency of the highest-priority power receiving device when supplying power to the power receiving devices as power supply targets including the highest-priority power receiving device;
• a power supply circuit configured to supply power to a plurality of power receiving devices;
• and
• a processor configured to:
• compute the power supply efficiency of the highest-priority power receiving device when supplying power to the power receiving devices as the power supply targets including the highest-priority power receiving device, from the information received by the communication device, and
• decide, based on the computed power supply efficiency of the highest-priority power receiving device, the power receiving devices as the power supply targets so that an estimated supplied power is within a power supply capacity of the power supply circuit when supplying power to the power receiving devices as the power supply targets including the highest-priority power receiving device, and
• control power supply so as to supply power to the decided the power receiving devices as power supply targets.
