Insulated Gate Bipolar Transistor (IGBT) as controllableswitch, has been applied widely.
绝缘栅双极二级管(IGBT)作为一种可控开关，获得了广泛应用。

A controllableswitch for interrupting the charging current is controlled when the charging currentexceeds a predetermined charging current threshold.
如 果该充电电流超过一个预给定的充电电流阈值，那么一个可控开关就被 控制以断开该充电电流。

For example, a transistor is a controllableswitch, but it is directional between the collector and emitter, and it has interactive control between the base and emitter.
