有低的差动输出阻抗绝大多数的线路驱动器，同时也固有地有低的共模输出阻抗，这样，低阻抗桥臂几乎无一例外地位于驱动器一侧。
Most line drivers with low differential output impedance will also have inherently low common-mode output impedances, so the low impedance arms of the bridge are almost always at the driver.
为了限制逆变器桥臂直通短路时故障电流的上升率，可以在装置的直流侧安装一种称为“环流保护电路”的附加电路。
In order to restrict the rising rate of fault current caused by short circuit on one arm of bridge of inverter, a kind of device named current loop protection circuit can be adopted.
