Abstract

The power supply device according to an embodiment comprises: a power conversion unit including first input terminals, a first capacitor connected between the first input terminals, a first output terminal that supplies output current to an electromagnet, a first power conversion circuit connected between the capacitor and the output terminal, and first wiring that electrically connects the capacitor and the power conversion circuit to each other; and a control device that controls the power conversion unit on the basis of current command values sequentially supplied from the outside. The control device detects the sequential two maximal current values or sequential two minimal current values of the current command values to estimate the frequency of the output current.
