当栅极电压高于MOSFET的阈值电压(Threshold Voltage)时,MOSFET处于导通状态,允许电流从漏极流入源极。漏极电压(Drain-to-SourceVoltage)是指漏极与源极之间的电压,是MOSFET的工作电压。在导通状态下,漏极电压一般低于或等于栅极电压。过高的漏极电压可能导致MOSFET损坏。因此,栅极电压是控制MOSFET导通状态的关键参数。

将“扫描电源%”旋钮调到0位置,启动测试后慢慢调高“扫描电源%”旋钮,使曲线超出250μA,则MOSFET已经开启,开启电压就是ID=250μA处的电压。如图57,实测开启电压为2.978V。

Then, the gate reliability of SiC MOSFET devices have been compared to that of Si power devices of similar ratings. The results reveal a higher reduction in the instantaneous gate-source voltage of SiC MOSFETs compared to that of Si devices under the same operating conditions. The gate-voltage...
Gate Threshold Voltage The “perfect MOSFET” we talked about earlier (Figure 8.1) started conducting the moment we raised the Gate voltage above ground (i.e., Source). But an actual MOSFET has a certain Gate threshold voltage“Vt.” This is typically 1–3 V for “logic-level” MOSFETs ...
