基于控制变量法的原理,在其中一条支路串入电感的同时在另一条支路串入低感电阻,由此消除了电感引入的寄生电阻对实验结果的影响。 |
Based on theprinciple of the control variable method, an inductor was inserted in one branch while a low-inductanceresistor was inserted in another branch , the influence of the parasitic resistance introduced by the series inductance on the experimental results was eliminated. |

然后分别对漏极电感 Ld、源极电感 Ls 和栅极电感 Lg 不匹配与并联电流分配的关系进行实验研究,实验结果表明: |

Ld 不匹配对并联器件的瞬态电流上升过程没有影响,但会在两个器件间造成环流,且在环流衰减的过渡阶段和稳态阶段 Ld 对电流分配具有不同的影响规律,Ls 不匹配使得电感较小的器件瞬态电流过冲增大,而 Lg 对器件并联电流没有影响。 |
The experimental results show that Ld mismatch has no effect onthe transient current rise process, but it can cause circulation between the two devices, and Ld hasdifferent influence laws on current distribution in the transition phase of circulation attenuation andsteady-state process, Ls mismatch increases the transient current overshoot in devices with small inductance, and Lg has no effect on the current of parallel devices |
