The transistor gate has a distinct advantage over the diode gate in that the transistor amplifies, as well as acts as a gate.
晶体管门电路比起二极管门电路来有一个显著的优点,那就是晶体管除了起门的作用外还能够放大。
The MOSFET input diode is controlled by an electric field in the gate region, thus the input impedance is always extremely high because there is no forward biased diode to lower the input impedance.
MOSFET的输入二极管是由一个电场控制在门区,因此总是输入阻抗非常高,因为没有正向偏置二极管,以降低输入阻抗。
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。
