To suppress a ripple contained in current flowing into a DC power supply during one-pulse control in a motor drive apparatus receiving electric power from the DC power supply. A motor drive apparatus 1 includes an inverter control device (10) provided with a one-pulse control mode in which, during one electrical angle cycle, a positive rectangular pulse voltage and a negative rectangular pulse voltage are applied, as gate drive signals, to a switching element corresponding to each phase. When performing the one-pulse control mode, the inverter control device (10) gradually increases or reduces a duty in a predetermined phase angle width at rising and falling edges of the rectangular wave voltage.
