摘要： PURPOSE:To obtain a stable regenerative brake torque controlling performance of a controller of an electric railcar by reducing the output voltage of a converter in a range that the ratio of the voltage to the frequency is not constant but it becomes constant voltage and variable frequency. CONSTITUTION:A slip frequency function generator 13 applies a slip frequency in response to the deviation between a speed command and an actual speed and an amplifying compensator 17 applies a slip frequency in response to the deviation between a current command and a motor current to a low priority circuit 14. An adder 9 adds the output of a pulse sensor 8 and the output of the priority circuit 14 and applies an output frequency command and a voltage command to a stationary converter 5. A converter voltage correcting circuit 18 outputs a signal for reducing the output voltage of a converter 2 in a range that inputs an inverter frequency and outputs a constant voltage and variable frequency. In this manner, a predetermined brake torque can be obtained at the regenerative brake time.

摘要： PURPOSE:To prevent the brake torque of an electric railcar by increasing a current limiting value command when a voltage and a rotary field frequency applied to an induction motor move from constant voltage and variable frequency range to variable voltage and variable frequency range. CONSTITUTION:A slip frequency generator 2 supplies a slip frequency command in response to the deviation between the output of a pulse generator 1 and a speed command 100 and in response to the deviation between a current limiting value command 102 and the current of an induction motor 6 to a low priority circuit 4. A controller 5 supplies a signal for controlling the rotary field frequency and a voltage command for controlling the applied voltage to a stationary inverter 14. A correcting circuit 20 outputs a correcting value in response to the current limiting value command while the ratio of the applied voltage/the rotary field freqeuency increases while the voltage and rotary field frequency applied to the motor 6 move from constant voltage and variable frequency range to variable voltage and variable frequency range.

CONSTITUTION: The secondary side of a main transformer 4 is divided into a plurality of parts, and the outputs of unit rectifiers U1WU5 which perform AC/DC conversion for the respective divided parts are connected in series in order to control the current flowing through main motors M according to a pattern. When the gate commands from the gate command G1 of the first unit rectifier U1 through the gate command G4 of the fourth unit rectifier U4 have been generated, the main motor current I is controlled according to a set DC pattern. On the other hand, when the gate command G5 of the fifth unit rectifier U5 is generated, first, a DC pattern changing command is generated, and after the DC pattern has been changed, the main motor current I is controlled.
