Motor driving apparatus |
摘要 |
A motor driving apparatus 1 having a converter 2, which receives AC voltage and converts it to 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 to a link section between the converter 2 and the inverter 3, and energy stored in the capacitor C8 is charged and discharged at arbitrary timing by the charge/discharge control circuit 7. The invention thus provides 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. |
