CONVERTER |
| 摘要 |
A converter includes a first bridge arm, a second bridge arm, a switch circuit and a voltage clamp circuit. The first bridge arm includes a first switch unit and a second switch unit that are electrically coupled in series at an output terminal. The second bridge arm includes two voltage sources that are electrically coupled in series at a neutral point terminal. The switch circuit is disposed between the neutral point terminal and the output terminal. The voltage clamp circuit is electrically coupled to the output terminal, the neutral point terminal, and one of a positive input terminal and a negative input terminal, and is configured to clamp voltage across the switch circuit. |
