<P>PROBLEM TO BE SOLVED: To provide an inverter controller for driving a motor of which the fluctuation amount of a motor current is reduced for further smaller size, lighter weight, and lower cost. <P>SOLUTION: The inverter controller for driving a motor of a small size, light weight, and low cost can be realized using a reactor and capacitor of small capacitance. Even if driving of a motor is difficult or impossible as an inverter DC voltage fluctuates significantly, a PN voltage correcting means keeps a voltage applied to the motor almost constant for maintaining driving of the motor. Further, a beat amount correcting means suppresses the fluctuation amount of a motor current so that a loss is reduced and the current capacitance of an element is reduced, resulting in the inverter controller for driving a motor of smaller size, lighter weight, and lower cost. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
