摘要： A motor driving apparatus (1) controls driving of a single-phase motor (12) that rotates a rotor (12a) in which permanent magnets are disposed. The motor driving apparatus (1) includes an inverter (11) that includes a plurality of switching elements, converts, by using the switching elements, a direct-current voltage into an alternating-current voltage and outputs the alternating-current voltage to the single-phase motor (12), a voltage detection unit (20) and a current detection unit (21) that each detect a physical quantity representing an operation state of the single-phase motor (12), and a control unit (25) that controls, in accordance with the physical quantities, the alternating-current voltage to be output from the inverter (11) to the single-phase motor (12).

摘要： To include a leak-current detecting unit 21 that detects a zero-phase current flowing from an electric-motor driving device 100, which drives an electric motor 5 with electric power from an alternating-current power supply 1, or the electric motor 5 to a ground E2, a leak-current control unit 22 that, on the basis of the zero-phase current detected by the leak-current detecting unit 21, generates a control signal having cyclicity synchronized with the alternating-current power supply 1, and an anti-phase generating unit 23 that generates an anti-phase current that is in anti-phase to the zero-phase current on the basis of the control signal from the leak-current control unit 22, and outputs the anti-phase current.

摘要： A motor driving apparatus (2) drives a single-phase motor (12) including asymmetric teeth (12e). The motor driving apparatus (2) includes an inverter (11) supplying alternating-current power to the single-phase motor (12), and when an output voltage of the inverter (11) is applied to the single-phase motor (12) so as to activate the single-phase motor (12), if an absolute value of a current flowing in the inverter (11) or the single-phase motor (12) exceeds a first threshold (Vth1), application of the output voltage is stopped and thereafter a polarity of the output voltage is reversed.

摘要： The device 100 includes a rectifier circuit 3 that converts alternating-current power from an alternating-current power supply 1 into direct-current power; a short-circuit unit 30 that short-circuits the alternating-current power supply 1 via a reactor 2 connected between the alternating-current power supply 1 and the rectifier circuit 3; and a control unit 20 that controls an ON/OFF operation of the short-circuit unit 30 during a half cycle of the alternating-current power supply 1. The control unit 20 includes a driving-signal generating unit 21 that generates a driving signal Sa that is a switching pulse to control the ON/OFF operation of the short-circuit unit 30; and a pulse dividing unit 23 that divides the driving signal Sa into a plurality of switching pulses.
