Abstract (en)
[origin: EP2716588A1] An elevator control system includes a converter (24) that converts an electric power from an AC power supply (20) to a DC power, a capacitor 26 that smoothes the DC power, an inverter (30) that converts the DC power to an arbitrary AC power by a gate drive circuit (60) performing on-off control of switching elements (31) and drives a motor (11) moving an elevator car (9), a gate power-source circuit (50) that generates a dc power on the basis of the AC power supply (20) and supplies the dc power to the gate drive circuit (60), a rechargeable battery (52) that supplies a dc power to the gate drive circuit (60) when the AC power supply (20) is lost, a voltage detection unit (80) that detects the output of the gate drive circuit (60), a determination unit (83) that determines whether or not the value of the detected voltage is a threshold value or smaller, and a supply switch (Se) that supplies the dc power from the rechargeable battery (52) to the gate drive circuit (60) when the detected voltage value becomes the threshold value or smaller.
