<p>A single-phase full bridge inverter comprising an input voltage DC link for receiving DC voltage, two series connections of controllable semiconductor switches (S 1 , S 2 ; S 3 , S 4 ), and an output filter. The output filter comprises first and second inductors (L 1 , L 2 ) having a first end and a second end, which first ends of the first and second inductors form the input connections of the output filter and the second ends of the first and second inductors form the output connections of the output filter, at least one filter capacitor (C 1 , C 2 ), and first and second filter switches (S 5 , S 6 ), wherein the first filter switch (S 5 ) is adapted to connect the second end (51) of the first inductor (L 1 ) to the input voltage DC link through the at least one capacitor (C 1 ), and the second filter switch (S 6 ) is adapted to connect the second (52) end of the second inductor (L 1 ) to the input voltage DC link through the at least one capacitor (C 2 ).</p> |
