Abstract: Method (1) for detecting an input channel configuration of a multi-channel inverter (100) having a plurality of input channels (CH 1 , CH 2 , CH i-1 , CH 1 , CH N-1 , CH N ). Each input channel is electrically connected with a corresponding power converter (C 1 , C 2 , C i-1 , C i , C N-1 , C N ) and, upon an operative installation of said multi-channel inverter, being operatively associated to a DC electric power source (S 1 , S 2 , S i-1 , S i , S N-1 , S N ). The method comprises the following steps: - selecting a reference input channel among said input channels; - controlling said power converters to allow an input current higher than a current threshold to flow along said reference input channel and to allow input currents lower than said current threshold to flow along one or more remaining input channels different from said reference input channel; - acquiring detection data (D) indicative of input voltages (V 1 , V 2 , V i-1 , V i , V N-1 , V N ) of said input channels; - performing a comparison between the input voltages of said input channels; - executing a determination procedure (DP) to determine a configuration status of said input channels based on a behavior of the input voltages of said remaining input channels with respect to the input voltage of said reference channel.

Abstract: A double-stage inverter apparatus for energy conversion systems (FIG. 1) and control method thereof, adapted to manage the operations of the on-board booster module so as to optimize the overall electrical efficiency of the system. Furthermore, the method according to the present invention allows the operations of said double-stage inverter to be managed when there is only one input channel, when there are multiple input channels called to operate both in parallel and also when there are multiple input channels called to operate independently from each other.
