摘要： The present invention is to provide a magnet coil drive control device that can efficiently suppress conduction noise while reducing the capacitance of a capacitor. A capacitor and an impedance element are arranged in series on the connecting line connecting the positive electrode line and the negative electrode line of a DC power supply, the connecting line between the capacitor and the impedance element is connected to one end of a magnet coil via a freewheeling diode, and the portion between the freewheeling diode and the one end of the magnet coil is connected to the positive electrode line or the negative electrode line by a switching element. Conduction noise caused by the driving current of the magnet coil can be suppressed by the impedance element, and the capacitance of the capacitor can be further reduced. Accordingly, the magnet coil drive control device can be made smaller in size.

摘要： The present invention relates to an alternating-current power supply device which can improve a power factor of an alternating-current load, realizes low cost and miniaturization, and recovers magnetic energy. The alternating-current power supply device includes a bridge circuit composed of four reverse conducting semiconductor switches, a capacitor that is connected between direct-current terminals of the bridge circuit and absorbs the magnetic energy at the time of cutting off the current, an alternating-current voltage source that is connected to the induction load in series and is inserted between alternating-current terminals of the bridge circuit, and a control circuit that gives a control signal to gates of the respective reverse conducting semiconductor switches and controls on/off states of the respective reverse conducting semiconductor switches. The control circuit simultaneously controls the on/off operation of the paired reverse conducting semiconductor switches positioned on a diagonal line of the four reverse conducting semiconductor switches composing the bridge circuit, makes a control so that when one pair of the two pairs is ON, the other pair is OFF, and switches the control signal in synchronization with a voltage of the alternating-current voltage source.

摘要： Motor control at faulted condition. A common rotor is driven by two stators each controlled by a power supply. Each stator comprises an auxiliary winding supplied by DC current to saturate a yoke section during normal operation. During a faulty short circuit at the windings of the first stator the power supply of the first stator is cut off and said yoke section is no more saturated, thereby increasing the total impedance of the main winding. Advantage: The damaged first stator produces less drag on the rotor. The rotor can keep running, driven by the second stator alone.
