BLOWER AND ELECTRIC DEVICE WITH SUCH BLOWER MOUNTED THEREON |
摘要 |
A supply current control circuit controls the voltage of a low-voltage direct-current power source so that the average current of an inverter circuit detected by a current detecting circuit becomes constant at a specified current value. Accordingly, characteristics that are little in the amount of change of air volume are obtained.
