Abstract
An embodiment control device includes a voltage controller configured to output an input current command value of a power factor correction (PFC) based on an output voltage and an output voltage command value of the PFC, a current controller configured to control an input current of the PFC by determining a switching duty of the PFC based on the input current command value, and a current command upper limit generator configured to output an input current command upper limit value of the PFC based on an input current limit value and an input current command offset value of the PFC, wherein the input current command upper limit value has an alternating current (AC) component.
