Abnormal state detecting circuit of inverter |
摘要 |
In an inverter circuit composed of arms of at least one pair, connected between positive and negative lines of DC power source and turned on or off alternately, an abnormal state detecting circuit compares the neutral potential of the pair of arms with the neutral potential of the DC power source, and discriminates the abnormal state of the switching operation of the arms if the comparison result becomes less than a prescribed value.
