Abstract
In a control apparatus for a power converter, a current obtainer obtains a current flowing through an inductor as an inductor current, and a voltage obtainer obtains an alternating-current voltage. A slope compensation unit generates, based on the alternating-current voltage obtained by the voltage obtainer, a slope compensation signal having a slope that depends on the alternating-current voltage, and adds the slope compensation signal to the inductor current obtained by the current obtainer. A current controller controls on-off switching operations of a switch in a peak current mode to thereby cause the inductor current, to which the slope compensation signal has been added, to follow a sinusoidal command current that depends on the alternating-current voltage.
