Inverter device with improved current detector

An inverter device comprising:

• a DC power supply;
• an inversion section connected via a DC power supply line to the DC, power supply to he supplied with DC voltage from the DC power supply, thereby delivering AC voltage, the inversion section having a plurality of switching elements;
• a current-detecting resistor provided between the switching elements and the DC power supply line, the current-detecting resistor having both ends;
• and
• a current detector detecting current on the basis of voltage developed across said both ends of the current-detecting resistor, the current detector including a voltage-dividing resistor connected between a level-shift power supply line having a predetermined level-shift voltage and one of the ends of the current-detecting resistor, the voltage-dividing resistor having a voltage-dividing point, the current detector further including an A/D converter having a pair of reference potential terminals and an input terminal, one of the reference potential terminals being connected to the other end of the current-detecting resistor, the input terminal being connected to the voltage-dividing point of the voltage-dividing resistor.
