<p>A method for controlling a switching branch of a three-level converter into a stop state, and a switching branch comprising a first semiconductor switch (S1) and a second semiconductor switch (S2), a first diode (D1) and a second diode (D2), a third semiconductor switch (S3) and a fourth semiconductor switch (S4), a third diode (D3), and a fourth diode (D4), a fifth semiconductor switch (S5) and a sixth semiconductor switch (S6), a fifth diode (D5), and a sixth diode (D6), and means (10) for controlling the semiconductor switches, wherein, when the switching branch is to be set into a stop state, current flowing in a main circuit of the switching branch is transferred in a controlled manner to diodes that conduct the current, when all the semiconductor switches of the main circuit of the converter are turned OFF.</p> |
