<P>PROBLEM TO BE SOLVED: To apply a mode of use, in terms of a DC driver to an AC inverter driver. <P>SOLUTION: A method for connecting a DC power supply to regeneration terminals 15a and 15b and continuously supplying DC, in a state with an input terminal 11 open is adopted for the AC inverter driver A, provided with the input terminal 11 to which the AC power supply 4 is connected, a rectifier circuit 2 converting an AC inputted from the input terminal 11 into a DC and supplying it to DC feed lines 13a and 13b, an inverter circuit 3 converting again the DC supplied to the DC feeding lines 13a and 13b into the AC, an output terminal 12 for connecting an AC motor 5, which is a load with respect to the inverter circuit 3, and regeneration terminals 15a and 15b for regenerating power, when power generated on a load side is supplied to the DC feeding lines 13a and 13b. <P>COPYRIGHT: (C)2011,JPO&INPIT |
