A power-saving driving device is provided for a device 23 having the same load pattern and driven by a motor 21 receiving electric power from an inverter 19. The power-saving driving device includes a DC-DC converter 93 driven by a battery 91 and the inverter driven by an output of the DC-DC converter. The power-saving driving device further includes an electric power amount W calculator 81 that calculates an electric power amount received from the battery in the same load pattern, and a parameter selection/instruction unit 83 that causes a parameter (carrier wave frequency instruction value F and output voltage instruction value G) of the inverter to change to be a plurality of values, compares the received electric power amounts respectively corresponding to the values of the parameter, selects the parameter value minimizing the received electric power amount, and instructs the selected parameter value to the inverter.
A power-saving driving device that is provided for a device having the same load pattern and driven by a motor receiving electric power from an inverter, the power-saving driving device comprising a DC-DC converter driven by a battery and the inverter driven by an output of the DC-DC converter, and further comprising:
A power-saving driving method that is performed for a device having the same load pattern and driven by a motor receiving electric power from an inverter, the power-saving driving method comprising the step of providing a DC-DC converter driven by a battery and the inverter driven by an output of the DC-DC converter, and further comprising the steps of:
A power-saving driving device that is provided for a device having the same load pattern and driven by a motor that receives electric power from a wireless electric power transmission device, the power-saving driving device comprising:
A power-saving driving method that is performed for a device having the same load pattern and driven by a motor that receives electric power from a wireless electric power transmission device, the power-saving driving method comprising the steps of:
