摘要： A converter and an inverter are connected via a clamp circuit. The converter performs commutation in accordance with any of a first commutation mode in which trapezoidal waves are compared with a carrier and a 120-degree conduction mode. A diode of the clamp circuit is short-circuited by a shorting switch. The shorting switch is rendered conductive when a power factor reduces or a power supply voltage reduces, and capacitors of the clamp circuit are connected in series between DC power supply lines. The converter performs commutation in accordance with the 120-degree conduction mode, not in accordance with the first commutation mode, while the shorting switch is conductive.

摘要： Controlled by switching is which reactor in a reactor group present between a power source and a three-level converter is to be connected to an intermediate point that outputs a midpoint potential. In the switching, the closer to the command value of the midpoint potential the command values of input potentials of the converter are, the greater the duty at which corresponding reactors are connected to the intermediate point is for pulse width modulation. Additionally, a predetermined range to be compared with the command values has a predetermined potential width with respect to an AC waveform centered around the command value of the midpoint potential.

摘要： A transistor is brought into conduction when, for example, a voltage between both ends of a second clamp capacitor exceeds a predetermined reference voltage. A resistance value of a discharge resistor is smaller than a value obtained by dividing the reference voltage by the maximum value of a current flowing through the discharge resistor. When the transistor is brought into conduction as a result of a voltage between both ends of the second clamp capacitor exceeding the predetermined reference voltage, a voltage applied to the discharge resistor, which results from a regenerative current, is larger one of the voltage between both ends of the second clamp capacitor and a voltage drop of the discharge resistor due to the regenerative current. The voltage drop and the voltage between both ends are smaller than a voltage between DC power supply lines, whereby it is possible to reduce an electrostatic capacitance of the discharge resistor.

This AC component has a frequency which is six times a fundamental frequency of an AC voltage outputted by the inverter.

摘要： A converter section converts a three-phase ac input voltage into a dc voltage, and an inverter section converts the dc voltage converted by the converter section into a prescribed three-phase ac output voltage. The converter section converts the three-phase ac input voltage into the dc voltage on the basis of trapezoidal waveform voltage instruction signals from a trapezoidal waveform voltage instruction signal generating part and a carrier signal from a carrier signal generating part. The inverter section converts the dc voltage converted by the converter section 1 into a prescribed three-phase ac output voltage on the basis of an inverter section instruction signal corrected by an instruction signal correcting part. The trapezoidal waveform voltage instruction signal generating part generates sloped regions of the trapezoidal waveform voltage instruction signals by using a prescribed table.
