Document Type and Number:
Japanese Patent JP5439262
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the following problem associated with conventional technologies in which all phases of an alternating-current motor are energized for discharging: when there is a phase in which a current cannot be passed for some reason due to a break, a failure in a switch incorporated in an inverter, or the like, there is a possibility that an unintended current is produced in the remaining phases.SOLUTION: When power is not supplied to an inverter 5, discharge of the capacitor 6 is carried out by consuming power in the winding of the alternating-current motor 3 by passing an alternating current of a short period between two phases of an alternating-current motor 3 by voltage accumulated in a capacitor 6 so that the alternating-current motor 3 does not rotate.
