<P>PROBLEM TO BE SOLVED: To provide an elevator control device for controlling to surely charge power of regenerative operation and effectively use the same for power running. <P>SOLUTION: This elevator control device is constructed by providing the general elevator control device consuming the generated power in the regenerative operation in a rheostatic chopper 18 with an electric double-layer capacitor 21 parallel-connected to a direct current capacitor 3 for smoothing the direct current ripple of a rectifying circuit 2 for rectifying alternating current of an alternating current power supply 1, having an electrostatic capacity larger than the direct current capacitor, and accumulating most of the regenerative power from the motor side; a voltage detecting circuit 22 for detecting the terminal voltage of the electric double-layer capacitor; and a drive control part 5 taking the voltage near the rated voltage of the electric double-layer capacitor as the operating voltage of the rheostatic chopper and controlling the operation of the rheostatic chopper when the terminal voltage detected in the voltage detecting circuit reaches the voltage near the rated voltage of the electric double-layer capacitor. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
