<P>PROBLEM TO BE SOLVED: To provide a motor control unit capable of reducing losses in batteries, converters, or the like, at driving of the converters, and of ensuring stability in current feedback control. <P>SOLUTION: The motor control unit includes a converter drive circuit 20, and the converter drive circuit includes a current control block 211, with a converter input current of a step-up converter 3 as current feedback control information, and generates a converter drive signal to the step-up converter 3. In the motor control unit, an input-side smoothing capacitor 31 is set by parallel connection to the battery 4 at an upstream position of a reactor 32; a DC current sensor 6 is inserted into a position from the battery 4 to the input-side smoothing capacitor 31; and the converter drive circuit 20 sets the current feedback control information used by the current control block 211 as DC current information acquired based on the sensor value from the DC current sensor 6. <P>COPYRIGHT: (C)2011,JPO&INPIT |
