Abstract: A switching branch for a three-level inverter, comprising a first and second switch (S1, S2) in series between a positive DC pole (P) and an AC pole (AC), a first and second diode (D1, D2) parallel to the first and second switches, a third and fourth switch (S3, S4) in series between a negative DC pole (N) and the AC pole, a third and fourth diode (D3, D4) parallel to the third and fourth switches, a fifth diode (D5) between a neutral DC pole (M) and a point between the first and second switches, a sixth diode (D6) between the neutral DC pole and a point between the third and fourth switches, a fifth switch (S5) and a seventh diode (D7) in series between the neutral DC and AC poles, and a sixth switch (S6) and an eighth diode (D8) in series between the neutral DC and AC poles.
