<p>The circuit has a first switching group system (1) per phase (R) with a power semiconducting switch (2) and capacitor (3) forming a first main switching group (4), an intermediate switching group (7) with two series power switches (5), such as IGBTs, and a capacitor (6) and a second main switching group (9). The power semiconducting switches (2,8) of the first and second main switching groups are passive, non-controllable electronic components with unidirectional current carrying directions.</p> |
