Turn-off of gate-controlled switch

机译:闸控开关的关闭

摘要

A gate-controlled switch configuration comprising a gate-controlled switch (V4) and a gate driver system (Ctrl, D1, D2, V1, V2), which in its first functional state is configured to change the amount of charge (Qgate) in the gate (G) of the gate-controlled switch (V4) to provide a normal turn-off functionality for the gate-controlled switch (V4), and in its second functional state it is configured to maintain the amount of charge (Qgate) in the gate (G) of the gate-controlled switch (V4) substantially constant. The gate driver system (Ctrl, D1, D2, V1, V2) is configured to produce a soft turn-off functionality during which the gate driver system (Ctrl, D1, D2, V1, V2) is in the first functional state a plural number of times, and between the subsequent first functional states it is in its second functional state.
