Abstract

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. It shares with the IGBT an isolated gate that makes it easy to drive. Power converters are pivotal components in modern electronic systems, facilitating the transformation of electrical energy from one form to another. Among the crucial elements within these converters, Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) play a central role due to their efficiency and versatility.
