How are MOSFET gate capacitances (Cgs, Cgd) calculated? 6 Your equations are approximations to the capacitance seen between G-D and G-S of a mosfet in different regions of operation and they are derived based on the physical characteristics of the mosfet Keep in mind that the physical mosfet is a symmetric device
mosfet - H-bridge driver - Electrical Engineering Stack Exchange If the mosfet is fully on it has high current low resisance and more power dissipation, but form many fets the Rdson is lower than 1Ω or in the mΩ range, so large currents will still dissipate heats that the package can handle The problem when the gate voltage is somewhere in the middle, and the resistance in the mosfet is equal to the load
MOSFET Power Supply Explained - Electrical Engineering Stack Exchange By my understating the MOSFET only amplifies current, not voltage, so how is the output changing with the jumpers? Edit: I understand now that the transistors are working as an amplifier to give a negative voltage potential to the FET I am now struggling to grasp how the current changing from the FET changes the output voltage
