У чому відмінність IGBT від Mosfet?

What is the difference between a MOSFET and an IGBT?

IGBT: Commonly used in high-power applications such as motor drives, power inverters, and induction heating systems. MOSFET: Widely used in applications where fast switching and efficiency at lower power levels are crucial, such as voltage regulators and electronic switching circuits.

Can I replace MOSFET with IGBT?

No, but you can build one from a MOSFET – Wikipedia and a Bipolar junction transistor – Wikipedia (BJT). The real IGBT structure is different, it's based on the Thyristor – Wikipedia structure. However, thyristor operation is suppressed. For all intents and purposes it works like a transistor.

Why is IGBT used in an inverter instead of MOSFET?

This is because the IGBT has lower switching losses and lower conduction losses than similarly rated MOSFETs.

What are IGBT used for?

IGBTs are widely used as switching devices in the inverter circuit (for DC-to-AC conversion) for driving small to large motors. IGBTs for inverter applications are used in home appliances such as air conditioners and refrigerators, industrial motors, and automotive main motor controllers to improve their efficiency.

Для інвертора на 160А IGBT транзисторів знадобиться 2-3 (в залежності від робочого циклу), а MOSFET – 10-12. От власне в чому і відмінність.
