<P>PROBLEM TO BE SOLVED: To reduce the switching loss of the switching element of an inverter, 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 voltage rise ratio constant control that keeps the voltage rise ratio of the capacitor voltage to battery voltage constant in case that the voltage of a battery is under specified voltage, and performs capacitor voltage constant control that keeps the voltage of the capacitor constant in case that the battery voltage is higher than the specified voltage. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
