PROBLEM TO BE SOLVED: To achieve high frequency of switching while suppressing an increase in cost, in a power conversion device.SOLUTION: A power conversion device includes: an inverter circuit (4) switching on and off of a plurality of switching elements (Su, Sv, Sw, Sx, Sy, Sz) and converting a direct current into an alternate current; and a control section (5) calculating output voltage command values (Vdc*, Vqc*) of the inverter circuit (4) in a predetermined control period (T), and generating a pulse according to the output voltage command values (Vdc*, Vqc*) in synchronized with a carrier signal (Ca) with a period (Tc) shorter than the control period (T) to control the on and off. |
