<p>PURPOSE: An air-conditioner is provided to enable a user to easily detect an excess current within a specific driving area and to control a circuit. CONSTITUTION: An air-conditioner comprises a power factor improving unit(112), a current detector(118), a power device(116), and a controller(120). The power factor improving unit is switched to output a current based on a DC power source created by rectifying an AC power source. The current detector detects current and outputs adetection current. The power device creates phase signals and outputs the phase signals to a compressor. The controller controls the power factor improving unit to prevent an excess current from being supplied to the power device.</p> |
