Abstract
A current sensing apparatus includes: a temperature sensor configured to sense a temperature of a power converter; a current sensing unit configured to sense an input current of the power converter; and a central processing unit (CPU) configured to control an operation of the power converter in response to the sensed temperature of the power converter and the sensed input current of the power converter. The CPU includes a compensation unit configured to store, upon receiving an indication of the sensed temperature of the power converter from the temperature sensor, an operation voltage of at least one diode included in the current sensing unit in a map, and to compensate for an error of a sensing current based on the stored operation voltage when the current sensing unit senses the input current.
