Zusammenfassung:	A method is provided for power limiting in a power inverter configured to produce an output voltage and having a voltage regulator with a voltage setpoint defined for no load on an external bus line. The method includes determining a power level related to a load on the external bus line, determining an adjusted voltage setpoint based on the power level, including: decreasing the voltage setpoint to the adjusted voltage setpoint having a first value when the power level is above a maximum threshold, increasing the voltage setpoint to the adjusted voltage setpoint having a second value when the power level is below a minimum threshold, and slewing the adjusted voltage setpoint to the voltage setpoint so that the adjusted voltage setpoint has a third value when the power level is within a range defined by the maximum threshold and the minimum threshold.
