摘要： A power converter circuit includes a diode group, a relay, a DC section and an inverter. The diode group includes a plurality of diodes arranged to rectify an output voltage of an alternating-current power supply. The relay is provided at a point located closer to the alternating-current power supply than the diode group. The DC section is where an output voltage of the diode group is applied. The inverter is arranged to output a three-phase alternating-electric current to a three-phase load. The DC section has a maximum pulse voltage twice as great as a minimum pulse voltage of the DC section. The DC section includes an energy-absorbing circuit having an electrolytic capacitor. The DC section further has a pathway arranged to apply the output voltage of the alternating-current power supply from the alternating-current power supply to the electrolytic capacitor via a rectifying circuit, not via the relay.

摘要： A voltage detection section and current detection section detect a voltage and current supplied to a motor, and the detected voltage and current are supplied to a position detection section. An angular speed output from the position detection section is supplied to a differentiator to output an angular acceleration. A fundamental wave component extraction section extracts a fundamental wave component of the angular acceleration, and the extracted fundamental wave component is supplied to an amplitude adjustment section. The output of the amplitude adjustment section is subtracted from the average current command by a subtraction section. This subtraction result, current detection value, and the rotor position from the position detection section are supplied to a current control section to carry out the current control operation so as to obtain a current command. The current command is supplied to an inverter to control the voltage and current so as to suppress the speed changing due to the load torque changing. Thus, stability is improved, and a decrease in cost is realized.

摘要： One field period includes a plurality of subfields each having (i) an initialization period in which a gradually descending sloping waveform voltage is applied to a scan electrode, (ii) a writing period in which a negative scan pulse voltage is applied to the scan electrode, and (iii) a sustain period. A sloping waveform voltage is generated by switching a minimum voltage in the sloping waveform voltage between a first voltage and a second voltage that has a lower voltage value than that of the first voltage. A number of subfields, in which an initialization is carried out by the sloping waveform voltage having the minimum voltage as the second voltage, is increased when a temperature of a plasma display panel is determined to be low as compared with when the temperature is determined to be not low.
