An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily forming an electronic switch. It is used to get high efficiency with fast switching.
Is IGBT bipolar or unipolar?
IGBT is a bipolar device that utilizes two types of carriers, electrons, and holes, resulting from the complex configuration that features a MOSFET structure at the input block and bipolar output.
What is the principle of IGBT?
In an IGBT, when a voltage that is positive with respect to the emitter is applied to the gate, the device enters the on state, and a collector current flows.
Is IGBT faster than BJT?
The IGBT is developed by combining the characteristics of a BJT and a MOSFET. The switching frequency of IGBT is very high compared to BJT. So it is faster than BJT.
IGBT is a NPN or a PNP?
An IGBT cell is constructed similarly to an n-channel vertical-construction power MOSFET, except the n+ drain is replaced with a p+ collector layer, So forming a vertical PNP bipolar junction transistor.
