<P>PROBLEM TO BE SOLVED: To provide an inverter device which can dissolve the inconvenience caused by the sudden rise of revolution of a motor that occurs at recovery after a drop in DC voltage. <P>SOLUTION: This inverter device, which converts the DC voltage into pseudo AC voltage so as to rotate the motor, raises the revolution of the motor 6, according to the specified rotating speed change rate condition, in case that DV voltage is recovered after drop of the revolution of the motor 6 by the drop of DC voltage. The DC voltage is one from a battery 1 or a generator being a power source for the main shaft motor for travel of an automobile, and the motor is one 6 for drive of a electric compressor for room air conditioning of an automobile. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
