ABSTRACT:
A current limiting circuit for a DC to AC inverter is provided with means for sensing the current in the inverter output phases and means for switching all of the power poles to the polarity of the minority power pole when an overcurrent condition occurs. This reduces the switching current levels of the inverter power pole switches to reduce switching stresses and improve reliability. A current sensing scheme is illustrated in which self-excited transductors are used to sense the current in two of the three inverter output phases and the current in the remaining output phase is derived from these two sensed currents.
