<p>A power-conserving drive device for a device (23) having a uniform load pattern, driven by a motor (21) supplied with power from an inverter (19), and operated by the repetition of the uniform load pattern, is provided with a DC-DC converter (93) driven by a battery (91), and the inverter (19) driven by the output of the DC-DC converter. The power-conserving drive device is provided with: a power volume computing unit (81) which measures the volume (W) of power received from the battery during a uniform cycle pattern; and a parameter selection/command unit (83) which converts the inverter parameters (carrier frequency command value (F) and output voltage command value (G)) into a plurality of values, compares the volume of power received for each parameter, selects the parameters which minimize the volume of power received, and commands the inverter to implement the parameters.</p> |
