| 摘要 |
The invention relates to a active-neutral point clamped converter having at least one half-bridge circuit connected into a DC voltage circuit. Each half-bridge circuit has a high-potential-side input half-bridge and a low-potential-side input half-bridge in series. The half-bridge circuit further has an output half-bridge connected between center taps of the input half-bridges. The total inductance within the output half-bridges and between the three half-bridges is dimensioned such that if any of the power semiconductors of the half-bridge circuit fails, a short-circuit can be reliably disconnected via a shorted circuit formed between the three half-bridges of the half-bridge circuit by the intact power semiconductors in said shorted circuit. |
