🧠 Functional Role
IGBTs are power semiconductor switches used to efficiently control large voltages and currents by combining the high‑current capability of bipolar transistors with the easy gate drive of MOSFETs. They’re common in high‑power electronics such as variable‑frequency drives (VFDs), industrial inverters, UPS units, and renewable energy converters.
🔧 Common Applications
-
AC and DC motor drives (VFDs) – for controlling industrial motors.
-
Three‑phase inverters – core switching blocks for converting DC to AC.
-
Uninterruptible Power Supplies (UPS) – high‑efficiency power conversion.
-
Solar/wind power inverters – energy conversion with high reliability.
