SiC MOSFET比 Si MOSFET 开关速度更快,所以 SiC 栅极驱动器的设计要求能够承受更高dV/dt(开关期间漏极-源极电压变化率)是非常关键的,因为这会对MOSFET造成振荡和损坏。在硬开关应用中,SiC MOSFET能够产生超过150 V/ns的dV/dt,所以推荐使用带有高CMTI 额定值的驱动器。 一些PCB布局建议及技巧 图2:SiC MOSFET抑...
Figure 8: Destructive short-circuit test of driver and SiC MOSFET Conclusion To conclude, SiC technology enables high-efficiency and high-power–density systems but must be driven with several strategies in mind. The gate driver must have a sufficient drive capability to reduce switching losses and...
By reducing turn-off spikes and ringing, both under normal operation as well as short-circuit (DSAT) conditions, SiC MOSFET modules can be safely operated in the higher frequencies that enable dramatic increases in power conversion density. ...
