The schottky diode bypasses the gate resistor in the gate discharge path, so that there is no falling edge delay. The delay at the rising edge adds dead time.
为了增加更多的死区时间，补偿功率管的切换瞬间短暂延时，增加了一个肖特基二极管，与栅极电阻。

The adjustment of circuit parameters can also induce over-resistence discharge and realize the function of diode.
