| 摘要 |
<p>The invention relates to a rectifier circuit having a rectifier unit (1), said rectifier unit (1) comprising a plurality of actuatable power semiconductor switches, the DC side thereof being connected to a capacitive energy storage circuit (2), wherein the capacitive energy storage circuit (2) comprises at least one capacitive energy store and at least one load shedding network (3) for limiting the rate of increase of the current or voltage at the actuatable power semiconductor switches of the rectifier unit (1). In order to reduce undesired oscillations of an overcurrent in the capacitive energy storage circuit, the capacitive energy storage circuit (2) comprises at least one passive, non-actuatable damping unit (4) having a unidirectional current passage direction, wherein the passive, non-actuatable damping unit (4) comprises a diode and a damping resistor.</p> |
