发明名称 MOTOR CONTROL APPARATUS INCLUDING AT LEAST TWO RESISTANCE DISCHARGE UNITS
摘要 A motor control apparatus includes a rectifier for rectifying AC power to output DC power; an inverter for performing power interconversion of DC power of a DC link and AC power being driving power or regenerative power of a motor by being connected to the DC link being a DC output side of the rectifier; and at least two resistance discharge units each for performing resistance discharge of DC power of the DC link, the resistance discharge units each being connected to the DC link, in which each resistance discharge unit starts a resistance discharge operation for performing resistance discharge of DC power of the DC link at a DC voltage value in the DC link exceeding a first threshold value and stops the resistance discharge operation at a DC voltage value in the DC link smaller than a second threshold value below the first threshold value.
