A braking device that calculates an electric braking force command in accordance with the braking command and generates a mechanical braking command, and a control circuit that calculates an electric braking force on the basis of the electric braking force command from the braking device and the braking command and controls the power converter, are provided. The control circuit includes a control calculating unit that calculates the electric braking force and controls the power converter, a virtual braking force calculating unit that calculates a virtual braking force to complement the electric braking force when starting braking, on the basis of the braking command and an output of a voltage sensor for detecting an input voltage to the power converter, and an adder that adds a calculation output of the control calculating unit and a calculation output of the virtual braking force calculating unit.

摘要: A controller for an AC rotary machine, by which a stable rotation angular-frequency estimate (AFE) value can be obtained even in an extremely low speed region of the AC rotary machine is disclosed, and consequently stable control can be performed. The controller includes an AFE outputter that outputs an AFE value based on an angular-frequency calculated value including a rotation AFE value. The AFE outputter includes a lower-limit constant-value (LLCV) outputter that outputs a LLCV, a comparator that compares the angular-frequency calculated value to the LLCV, and a switcher that performs a switching operation according to the comparator. The switcher outputs the angular-frequency calculation value as the AFE value when the angular-frequency calculation value is larger than the LLCV, and outputs the LLCV as the AFE value when the angular-frequency calculation value is equal to or less than the LLCV.

摘要: An electric vehicle controller includes a speed sensorless vector controller for estimating the rotating speed of an AC motor from an output voltage command and an output current from a VVVF inverter, and controlling the VVVF inverter based on the estimate. An overhead wire current detector detects the current flowing through an overhead wire. A wrong action sensor senses an abnormality in the speed sensorless vector controller from the sign of the current flowing through the overhead wire and detected by the overhead wire current detector when the VVVF inverter is in operation. A gate stop circuit stops the VVVF inverter when the wrong action sensor senses an abnormality.

摘要: A control apparatus for an electric railcar includes an inverter that exchanges power with an AC rotating machine, a filter capacitor connected in parallel to a DC side of the inverter, a filter reactor provided between the filter capacitor and an overhead line, an overhead line voltage measuring instrument that measures a voltage value of the overhead line, a voltage increase detection unit that senses an amount of voltage increase occurring when, with an overhead line voltage being supplied, the overhead line voltage goes beyond a reference voltage value and rises at a rate equal to or higher than that by a predetermined time constant. A correction torque command value calculation unit calculates a correction torque command value that is corrected so that a torque command value to be received from an external unit becomes smaller for a predetermined time elapsing after the voltage increase detection unit has sensed, during regeneration operation of the inverter, an amount of voltage increase more than a predetermined range. A vector control unit controls the inverter so that the AC rotating machine develops torque coincident with the correction torque command value.
