Abstract:
An inverter, comprising:a switching bridge for converting direct current into alternating current, the direct current being coupled to a line side of the switching bridge and the alternating current being provided at a load side of the switching bridge;a switching pattern generator for controlling switches in the switching bridge based on a reference current;at least one output filter capacitor connected at a terminal thereof to the load side of the switching bridge, said terminal being connectable to a load having an inductance;a control loop, connected to the switching pattern generator, for(a) measuring the load current or voltage and based on an error associated therewith generating a nominal reference current,(b) determining a damping current based on the voltage at said terminal, and(c) determining the reference current supplied to the switching pattern generator by subtracting the damping current from the nominal reference current.
