PROBLEM TO BE SOLVED: To prevent a DC voltage of a DC link part from being dropped.SOLUTION: A control section (40) controls a switching operation of an inverter circuit (13) in such a manner that magnetic energy stored in an inductance component of a motor (30) by decreasing a current quantity of motor currents (i, iand i) is regenerated to a DC link part (12) via the inverter circuit (13) during a regenerative operation period (P1). |
