POWER CONVERTING APPARATUS AND METHOD OF SENSING OUTPUT CURRENT THEREOF

A power converting apparatus includes a power converter, a first resistor, a second resistor, a current controller, a voltage sensor, a sample/holder, and a switch controller. The power converter converts an input voltage into an output voltage. The first resistor is connected to an output of the power converter, and the second resistor is connected to the first resistor. The current controller controls a first current to make the first current that is less than a second current flowing in the first resistor flow in the second resistor, and outputs a third current corresponding to the first current. The voltage sensor senses a first voltage corresponding to the third current. The sample/holder samples the first voltage, and outputs the sampled voltage. The switch controller controls an operation of the power converter based on a voltage output from the sample/holder.
