    • PROBLEM TO BE SOLVED: To suppress the rise of a terminal voltage caused by the overcharging of a smoothing capacitor, when all switching elements that constitute a voltage-type inverter are controlled into off-states. SOLUTION: This inverter device for motor drive comprises: a rectifier 2 that rectifies an AC voltage; the smoothing capacitor 3 that smoothes a DC voltage output by the rectifier 2; and the voltage-type inverter 4 that converts main circuit voltages appearing at both ends of the smoothing capacitor 3 into AC voltages applied to a motor 5 by the switching operation of the semiconductor switching element. The inverter device also comprises a control means that makes the semiconductor switching element constituting the voltage-type inverter 4 conduct the switching operation so that a current flows to the motor 5 when the main circuit voltages appearing at both the ends of the smoothing capacitor 3 become higher than a threshold voltage, when the semiconductor switching elements that constitute the voltage-type inverter 4 stop their swithcing operations.

    • PROBLEM TO BE SOLVED: To detect the upper lower short-circuit of an inverter circuit by determining the presence of abnormality from the outputs of the first comparator which judge whether detected voltage is near a positive electrode and the second comparator which judges whether it is near a negative electrode, and the output of an ignition signal which on/off-controls a semiconductor element for switching. SOLUTION: A control means 10a determines the presence of abnormality in self-arc-extinguishing element 51a, 51d and a circuit which outputs an ignition signal to the self-arc-extinguishing elements 51a, 51d from the outputs of a comparator 11a (the first comparator which judges whether output voltage VO is near a positive electrode) for VP and a comparator 12a (the second comparator which judges whether output voltage VO is near a negative electrode) for VN, and from the output of an ignition signal which on/off-controls the self-arc-extinguishing elements 51a, 51d as a semiconductor element for switching. If any abnormality is found, switching of a semiconductor element for switching which faces the semiconductor element for switching which had abnormality is shut down by a shunt-down circuit.
