    • PROBLEM TO BE SOLVED: To provide an inverter control unit for driving an induction motor of which the amount of fluctuation of a motor current is reduced for smaller size, less weight, and lower cost. SOLUTION: Driving of an induction motor 4 is maintained by keeping a voltage applied to the induction motor 4 almost constant using a PN voltage correcting means 10, even if driving of the induction motor 4 is difficult or impossible as an inverter DC voltage fluctuates much with the use of a small capacitance reactor 5 and a small capacitance capacitor 6. The phase angle of a motor voltage command correction value is corrected by a second motor voltage command correcting means 13 based on the DC voltage detection value of an inverter 3 which is acquired from a PN voltage detecting means 9.
