<P>PROBLEM TO BE SOLVED: To provide a power saving drive device and method for apparatus with the same load pattern, capable of minimizing loss amount in consideration of loss characteristics of all components without acquiring data of the loss characteristics by previously experimenting an output voltage of a DC-DC converter, electrical characteristics of a wiring, presence/absence of electromagnetic noise removal element, and loss characteristics and temperature changes for each motor. <P>SOLUTION: The power saving drive device includes: a DC-DC converter 93 driven by a battery 91 and an inverter 19 and is used for an apparatus 23 with the same load pattern, which is driven by a motor 21 whose power is supplied from the inverter and which is repeatedly operated in the same load pattern. Moreover, the power saving drive device also includes an electric energy calculator 81 which calculates received electric energy W from the battery in the same load pattern and a parameter selection and command device 83 which changes parameters (a carrier wave frequency command value F and an output voltage command value G)of the inverter into a plurality of values, compares received electric energy in the respective parameters and minimizes the received electric energy. <P>COPYRIGHT: (C)2012,JPO&INPIT |
