Abstract (en)
[origin: WO2020115360A1] According to an aspect, there is provided an inverter (100). The inverter (100) comprises a DC source (102); a power conversion unit(104); and an output filter unit (106) comprising at least one nonlinear inductor (108) configured for two operating areas, wherein the at least one nonlinear inductor (108) comprises a changing inductance value, the changing inductance value first configured for operation in a first operating area and configured to change to a different inductance value for operation in a second operating area before core saturation;and wherein the power conversion unit (104) is configured to receive a DC input from the DC source(102)and to provide an AC output filtered by the output filter unit(106).
