A controller of an embodiment includes a limiter receiving an active current command initial value, limiting a maximum value of the active current command initial value with a predetermined value, and outputting a first value; a circuit to calculate a reactive current command initial value; a calculator to calculate a reactive current command adjustment value; a unit receiving the first value as an input, and calculating a reactive current upper limit value such that a composite value of the first value and the reactive current upper limit value is equal to or smaller than an input current maximum value; and a limiter to output the reactive current command adjustment value or the reactive current upper limit value, whichever is smaller. The predetermined value is a value to set the reactive current upper limit value to a value larger than zero and smaller than the input current maximum value.
