<P>PROBLEM TO BE SOLVED: To reduce a ripple current which flows to a capacitor, in a system which supplies a motor with power, considering a capacitor provided between the positive electrode bus and the negative electrode bus of the inverter as a DC power source. <P>SOLUTION: This controller performs capacitor voltage constant control that keeps the voltage of the capacitor voltage constant in case that the voltage of a battery 1 is under specified voltage, and performs voltage rise constant control that keeps the voltage ratio of the voltage of the capacitor 4 to the battery voltage constant in case that the battery voltage is higher than the specified voltage. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
