DISCHARGING DC LINK CAPACITORS IN AN NPC CONVERTER |
摘要 |
A method is disclosed in one embodiment for discharging DC link capacitors. In one form the method includes switching a first half bridge of a first converter unit to a positive state, in which its AC output is connected with its positive DC output, and simultaneously switching a second half bridge of a second converter unit to a negative state, in which its AC output is connected with its negative DC output, such that a DC ink capacitor of the first converter unit and a DC link capacitor of the second converter unit are interconnected oppositely to each other arid discharged via the electrical filter. |
