摘要： Provided is a controlling device for a railway electric car, the controlling device being able to detect a slipping/sliding phenomenon during, in particular, high-speed travel and to exercise slipping/sliding control in an appropriate manner. A slip controlling unit 1 includes a first adhesion level index generating unit and a second adhesion level index generating unit. In a normal slipping state in which an acceleration changes instantaneously, torque control is exercised by using a first adhesion level index generated by the first adhesion level index generating unit based on an acceleration deviation and a speed deviation. In a slipping state during high-speed travel, because the acceleration deviation and the speed deviation are small, torque control is exercised by using a second adhesion level index generated by multiplying the first adhesion level index by a gain equal to or smaller than 1 generated by the second adhesion level index generating unit.

摘要： A pulsed power supply device in which a capacitor (23) having a charged voltage is discharged quickly upon closure of a switch (24). First and second series circuits (51, 52) are connected to each other in series and provided between the output terminals of a DC voltage source (2). The first series circuit (51) is a series circuit of a first reactor (14) and a first forward-direction diode (15), and the second series circuit (52) is a series circuit of a second forward-direction diode (16) and a switch (24). A third series circuit (53) that is a series circuit of a capacitor (23), a second reactor (25), and a discharge tube (9) is connected in parallel to the second series circuit (52). Upon closure of the switch (24), the discharge tube emits light and, on the other hand, the capacitor (23) is discharged to produce an oscillation current, whereby a voltage develops across the capacitor (23) in the polarity opposite to the polarity at the time of the initial charging. Since this voltage is added to a power source voltage and reused in the next charging cycle, the pulsed power supply device has a high efficiency.

摘要： A first threshold is determined, with reference to an absolute acceleration that is determined in accordance with a vehicle usage condition, to detect an acceleration change generated in acceleration of a self-axle speed that is a maximum speed (a minimum speed in a decelerating operation) of revolving speeds of plural motors that drive plural driving wheel axles. When the acceleration exceeds the first threshold, a system for generating a target torque command value reduced in accordance with the acceleration deviation is separated by setting an output of a comparator circuit to level “0”, and a first-order delay circuit outputs the target torque command value subjected to a reduction process during a processing period designated by an output of a delay time generating circuit.

摘要： A small-sized pulsed power supply unit capable of being manufactured at low cost. A switch (4) is connected in parallel to a capacitor (5) and a discharge load (6) in such a manner that it forms a closed circuit together with a DC voltage source (1) and a reactor (2) when the switch (4) is turned on, so as to store electromagnetic energy in the reactor (2), and a closed circuit together with the reactor (2), the capacitor (5) and the discharge load (6) when the switch (4) is turned off, so as to charge the electromagnetic energy stored in the reactor (2) to the capacitor (5) as electrostatic energy at a charge voltage higher than an output DC voltage of the DC voltage source (1). A voltage detector (7) detects the voltage of the DC voltage source (1), and a current detector (8) detects a current flowing through the reactor (2). A control circuit (9A) switches on and off the switch (4) based on the detected voltage and the detected current.
