The first stage: -48V power supply to charge C1, the charging formula is as follows.
Uc=48*R1/(R1+R2)[1-exp(-T/t)], where T is the time for the voltage of capacitor C1 to rise to Uc, and the time constant t=(R1//R2)C1. Therefore, the time required from power-on to turning on the MOS tube is: Tth=-t*ln[1-(Uc*(R1+R2)/(48*R1))]
The second stage: After the MOS tube is turned on, the drain current begins to increase, and its change speed is proportional to the transconductance of the MOS tube and the rate of change of the gate-source voltage. The specific relationship is: dIdrain/dt = gfm *dVgs/dt, where gfm It is the transconductance of the MOS tube, which is a fixed value, Idrain is the drain current, and Vgs is the gate-source voltage of the MOS tube. During this period, it is reflected in the constant control of the gate-source voltage on the drain-source current. The MOS tube is classified as a voltage-controlled type. Devices also come from this.
