Abstract

A power converting apparatus is comprised of an inverter unit arranged by a switching semiconductor element 51a for an upper arm and another switching semiconductor element 51d for a lower arm, and for turning ON/OFF the switching semiconductor elements to thereby convert DC power inputted from a DC power supply into AC power; and control means 10a for judging as to whether or not an abnormal operation is present based upon an output of a comparator 11a for judging as to whether or not a detection voltage detected by a voltage detecting circuit 61 is substantially equal to a voltage of the positive polarity; an output of a comparator 11b for judging as to whether or not a detection voltage detected by the voltage detecting circuit 61 is substantially equal to a voltage of the negative polarity; and an output signal of an igniting signal for ON/OFF-controlling the switching semiconductor elements, this voltage detecting circuit 61 detecting an output voltage of the inverter unit via a voltage dividing resistor, while using as a reference a potential at the positive polarity of the DC power supply, or a potential at the negative polarity thereof.
