Abstract (en)
[origin: WO2018193003A1] A converter device (26) comprises at least two half-bridge modules (10), each half-bridge module (10) comprising two semiconductor switches (12, 14) connected in series between a DC+ output (16) and a DC- output (18) and providing an AC output (20) between them; wherein the half-bridge modules (10) are connected in parallel with each other, such that the DC+ outputs (16) are connected with each other, the DC- outputs (18) are connected with each other and the AC outputs (20) are connected with each other; and wherein at least one of the half-bridge modules (10) comprises a current sensor (30) adapted for detecting a differential current signal (32) of a differential current between the DC+ output (16) and the DC- output (18), the differential current being a difference between a current into the DC+ output (16) and a current out of the DC- output (18).
