Input, DC, Output Inductors.
Current harmonic and dv/dt mitigation
– Limit input current peaks on the input circuit of the inverter
limit di/dt due to the input rectifier and to the capacitive load of the capacitors set;
– Reduce supply harmonic current;
– Increase power factor, thus reducing line current;
– Increase the duration of line capacitors inside the inverter.
– The output inductors reduce the dv/dt on motor cable and windings.
