Gate charge
WebSep 19, 2024 · Charge is charge - basically how many electrons (coulombs in SI units) need to be pushed/pulled in/out the gate to do something. It varies a lot because test … WebQG(TOT), Total Gate Charge It is the amount of charge required during MOSFET turn−on or turn−off transient. The charge is current multiplied by time (Q=I*t). It means the higher QG(TOT) requires the higher gate drive current within the same time or the longer time with the same gate current for the gate

WebTOTAL GATE CHARGE (Qg) First, a typical high power Mosfet “Gate Charge versus Gate-to-Source Voltage” curve will be ex-amined. An IRFP460 device has been selected and this curve is applicable to most other Fet devices by adjusting the gate charge numbers accordingly. Both turn-on and turn-off trasnsitions are shown with WebQG is the total gate charge QGS is the gate-to-source charge QGD is the gate-to-drain Miller charge QOD is the “overdrive charge” after charging the Miller capacitance. The curve of Figure 1 is typical of those supplied by MOSFET manufacturers. Notice that in order to achieve strong turn-on, a V GS well above that required to charge C EI ...
