摘要:
An elevator control apparatus includes a converter, an inverter, a controller for controlling a motor based on AC power having a variable voltage and a variable frequency supplied from the inverter and operating an elevator; a power storage unit for storing DC power; a charge/discharge control circuit that issues a drive signal such that discharge from the power storage unit increases within a range of power that can be discharged when an elevator is driven immediately following completion of uniform charging; and a charge/discharge circuit for charging the power storage unit in accordance with the drive signal. This arrangement permits quick discharging while effectively using discharge electric power until a state of charge is reached wherein regenerative electric power can be used for charging.
