<P>PROBLEM TO BE SOLVED: To provide a motor driving apparatus that supplies energy to a motor so that the peak of the input current from a power supply to the motor can also be suppressed, when particularly large energy is needed during the second half period of motor acceleration. <P>SOLUTION: The motor driving apparatus 1, having a converter 2 which receives an AC voltage and converts it into DC power, and an inverter 3, which receives the DC power and converts it to AC power, includes a charge/discharge control circuit 7 and a capacitor 8, connected in parallel with a link section between the converter 2 and the inverter 3, and energy stored in the capacitor C8 is charged and discharged with an arbitrary timing by the charge/discharge control circuit 7. <P>COPYRIGHT: (C)2009,JPO&INPIT |
