<p>An injection molding machine including a power supply regenerative converter 10 connected between an AC power supply 20 and inverter parts 30 is provided with a electric power conversion part 11 which bidirectionally converts between an AC power and a DC power, a DC voltage detector 15 which detects a DC voltage of a capacitor 14 between the inverter parts 30 and the electric power conversion part 11, and an AC control part 16 which outputs a control signal, which is produced based on the DC voltage detected by the DC voltage detector 15 and time variance of the DC voltage, to the electric power conversion part 11, and controls an alternating current flowing between the AC power supply 20 and the electric power conversion part 11.</p> |
