摘要
A method for controlling a switching branch for a three-level rectifier, and a switching branch comprising a first diode (D1) and a second diode (D2) connected in series, a third diode (D3) and a fourth diode (D4) connected in series, a first controllable switch (S1) connected between a neutral DC output pole (NP) and a connection point between the first and the second diode, and a second controllable switch (S2) connected between the neutral DC output pole (NP) and a connection point between the third and the fourth diode, means (10) for controlling the first controllable switch (S1) to be in a conductive state during a reverse blocking state of the first diode (D1) and the second diode (D2), and means (10) for controlling the second controllable switch (S2) to be in a conductive state during a reverse blocking state of the third diode (D3) and the fourth diode (D4).
