A power MOSFET is a specific type of metal–oxide–semiconductor field-effect transistor (MOSFET) designed to handle significant power levels. Compared to the other power semiconductor devices, such as an insulated-gate bipolar transistor (IGBT) or a thyristor, its main advantages are high switching speed and good efficiency at low voltages.
A power MOSFET is a voltage controlled device and it requires a very small amount of input voltage. When we call it as a voltage controlled device, then input should be voltage. Also we always assume gate current negligible because gate is insulated.
A Power MOSFET is a specialized MOSFET designed for high power applications. It offers fast switching speeds and superior performance at low voltages compared to standard MOSFETs. Its fundamental operating principle remains the same as that of general MOSFETs.
In this tutorial we will look at using the Enhancement-mode MOSFET as a Switch as these transistors require a positive gate voltage to turn “ON” and a zero voltage to turn “OFF” making them easily understood as switches and also easy to interface with logic gates.
This article discusses about What is a Power MOSFET, Working, Operation, power MOSFET Amplifier Circuit, Characteristics and their Applications
A power MOSFET is a type of metal-oxide-silicon field-effect transistor designed to operate at voltages up to 1 kV (or 2 kV in the case of SiC) while offering high switching speeds and optimal efficiency.
Power MOSFETs have become the standard choice as the main switching device for low-voltage (<200 V) switchmode power-supply (SMPS) converter applications. However using manufacturers’ datasheets to choose or size the correct device for a specific circuit topology is becoming increasingly difficult.
With power MOSFETs finding increasing use in portable electronics and wireless communications where battery power is at a premium, the trend is toward lower values of RDS(on) and Vth.
