Abstract

The invention relates to a controller arrangement (100) for controlling operation of an inverter in form of a switched-mode electrical power inverter, the controller arrangement having a control structure (106) comprising: a switching-element control-signal unit (180), that is configured to generate and provide a switching-element control signal (182) for controlling switching elements of the inverter. According to the invention, the control structure (106) further comprises: a transformation-control-computation unit (108), that is configured to determine and provide from a transformed three-phase voltage signal (102) and a reference voltage signal (104), a transformed voltage-control signal (110) in a synchronous-rotating reference frame of a fundamental frequency of the three-phase AC output voltage; and one or more resonant-control elements (120.1, 120.2, 120.n, 140.1, 140.2, 140.n), that receive the transformed voltage-control signal (110) and that are configured, using the transformed voltage-control signal (110), to provide a voltage-correction signal (122.1, 122.2, 122.n, 142.1, 142.2, 142.n) for use in generating the switching-element control signal (182).
