    摘要: A method and an arrangement for operating a storage and retrieval unit (3) are specified. A rail line (1) respectively a power supply rail (6) for the storage and retrieval unit (3) is set to a risk mode voltage, the rectified value/effective value of which lies below a minimum rectified value/minimum effective value necessary to move the storage and retrieval unit (3) but above zero, if a risk posed by the storage and retrieval unit (3) is detected. Alternatively or in addition, the voltage applied to the rail line (1)/power supply rail (6) can also be investigated in the storage and retrieval unit (3) for modulated change signals. The applied voltage is passed on to a traction motor (5) of the storage and retrieval unit (3) only when it has been established that the normal operation-traction voltage and not the risk mode voltage has been applied to the rail line (1)/power supply rail (6).

    摘要: According to one embodiment, four VVVF main circuit inverters for supplying electric power to drive a permanent-magnet synchronous motor are packaged into one unit. The four VVVF main circuit inverters are configured as a 4-in-1 inverter unit which shares a cooling mechanism for radiating heat generated due to power supply operation for the permanent-magnet synchronous motors to outside. A 2-in-1 semiconductor device package in which two semiconductor elements to convert electric power are packaged into one unit to be able to drive a permanent-magnet synchronous motor is contained in the 4-in-1 inverter unit. Thereby, individual control of inverters and reducing the size of the entire apparatus can be achieved for the electric-vehicle control apparatus.

    摘要: A power conversion device includes: an inverter that drives an alternating-current motor by converting a direct-current voltage into an alternating-current voltage of an arbitrary frequency; an alternating current disconnecting switching unit connected between the inverter and the alternating-current motor; a current detector that detects an output current of the inverter; and a controller that performs on/off-control of the plural switching elements in the inverter and switching control with respect to the switching unit, based on at least a current detected by the current detector. The controller has a configuration to be able to interrupt a fault current by setting the fault current to a state of generating a current zero point, when the fault current containing a direct-current component is generated between the inverter and the alternating-current motor.

    摘要: A railroad vehicle (1500) for carrying freight is described. The railroad vehicle (1500) comprises power regeneration capability through a traction motor (1530) linked to a driving wheel (1520D), an electrical energy storage system (1550), a controller (1570) that may selectively operate the traction motor (1530) in a motoring mode, a coasting mode, or a dynamic braking mode. In the dynamic braking mode electrical energy from the traction motor (1530) is transmitted to the electrical energy storage system (1550). The controller (1570) is in communication with a communication link (1580) that receives control commands from an external control source (1595), and those control commands indicate the operating mode for a particular period of time.
