<P>PROBLEM TO BE SOLVED: To provide a method of controlling an output current of an inverter, which can sufficiently reduce the output current error of the inverter. <P>SOLUTION: A control unit 3 calculates the error of the output voltage vB of the inverter at the point t(k-1) of time by expression (1) and superposes this output voltage error Err(k-1) on the average voltage command vB(k)* or vB(k+1)* or the like of the inverter in the period on and after the point t(k) of time, whereby it compensates the output voltage error thereby sufficiently suppressing the error of an actual current value (is). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
