A power supply apparatus for operation for outputting power to a surgical instrument includes a phase difference detection section for detecting a phase difference between an output voltage and an output current in the output, and an abnormality detection section for detecting an abnormality according to whether or not a period of time for which the phase difference deviates from a predetermined normal value range exceeds a predetermined period of time. Further, a power supply apparatus for operation for outputting power to a surgical instrument includes a phase difference detection section for detecting a phase difference between an output voltage and an output current from the power in the output, and an abnormality detection section for detecting an abnormality according to whether or not a variation value of the phase difference per unit time exceeds a predetermined threshold. By detecting the abnormality in this manner, the surgical instrument can be prevented from being broken.
