1. Understanding Gallium Nitride (GaN) and Its Role in Modern Power Electronics The power semiconductor landscape is undergoing a structural shift driven by the need for higher energy conversion efficiency, smaller form factors, and reduced thermal dissipation. For decades, conventional silicon (Si) devices—such as silicon Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) and Insulated-Gate Bipolar Transistors (IGBTs)—have served […]
What the IGBT Is and Its Industry Significance The Insulated Gate Bipolar Transistor, commonly abbreviated as IGBT, is a three-terminal semiconductor power switch that combines the high-impedance voltage control of a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) with the high-current conduction capability of a Bipolar Junction Transistor (BJT).
