Reliable as the significant feature of Grid, Firstack's drivers employ short-circuit protection technology to help the grid operate firmly.
As is the timing control of the inner and outer IGBT, especially in the short-circuit state, the earlier the short-circuit protection is performed, the safer the inner and outer IGBT of the NPC I-type 3-level are. The intelligent gate driver uses a fast short-circuit detection technology based on di/dt, the basic principle of which is shown in Figure below.
