1. How does a MOSFET work?

When a sufficient forward voltage is applied to the gate relative to the source, a conductive channel is formed on the silicon surface under the insulating layer, allowing current to flow from the source to the drain. For an N-channel enhancement MOSFET, the channel begins to conduct when Vgs (gate-source voltage) exceeds the threshold voltage Vth; for a P-channel MOSFET, the opposite is true.
2. How does a MOSFET work in an inverter?

In an inverter, a MOSFET is used as a switching element, quickly turning the circuit on or off according to the control signal, thereby converting DC power to AC power.
3. What are the 4 types of MOSFETs?

N-channel enhancement type.
N-channel depletion type.
P-channel enhancement type.
P-channel depletion type.
4. Is MOSFET 3-terminal or 4-terminal?

Basically, MOSFET is a three-terminal device (source S, drain D, and gate G). But in some cases, such as some high-voltage and high-power MOSFETs, there may be additional terminals (for example, substrate terminal B) to improve performance or reliability, so it is sometimes called a four-terminal device.
