The proper reasons for the unbalance are the unique structure of NPC three level converters and the parasiticinductance in the circuit.
并指出电压不平衡是由于NPC三电平的特殊结构和电路中的杂散电感造成的。
2
The approximate expression of parasiticinductance of flat line and twisted pair line is proposed after the study of parasiticinductance in the AC bus.
通过对母线的寄生电感分析，给出了扁平线和双绞线寄生电感的近似表达式。

The benefits of the passive components embedded into the circuit board not just save the space of the circuit board, but also reduce parasiticinductance.
