摘要： A method and an arrangement are disclosed for balancing load between parallel connected inverter modules, which inverter modules are arranged to supply a common load. The method can include providing similar switching instructions for parallel connected inverter modules, determining on the basis of phase currents of each parallel inverter module a first time period for each output phase of each inverter module for correcting current imbalance by advancing or delaying turn-on or turn-off time instants of switch components of the inverter modules, and advancing or delaying the turn-on or turn-off time instants of the switching instructions based on the first time period. The method also can include determining temperatures of each output phase of each inverter module, modifying the switching instructions for one or more of the parallel inverter modules for controlling the temperatures of the output phases, and controlling the inverter modules with a switching instruction in which the turn-on or turn-off times have been advanced or delayed in respect of one or more parallel modules and further modified in respect of one or more inverter modules.
