摘要：
To reduce total power required to drive an elevator by a commercial power supply during a peak power-consumption time period, for instance, an afternoon in summer time, a control apparatus includes a converter for rectifying AC electric power into DC electric power; an inverter for inverting the DC electric power into AC electric power having a variable voltage and a variable frequency; a motor driven by the AC electric power having the variable voltage and the variable frequency to operate an elevator; a power storage apparatus for storing electric power; and a charge/discharge control for controlling charging and discharging operation of the power storage apparatus based upon a charging target value.
