The full form of igbt is insulated gate bipolar transistor.
it is constructed from the combining of both BJT and PMOSFET.
it has high input impedance and low on - state power loss .
it is free from second break down problem present in bjt...
it is also known as (MOSIGT), (COMFET)...
it is constructed virtualy in the same manner as a power
MOSFET.an IGBT has also thousand of basic structure cells
connected appropritely on a single chip of silicon.
it has a four substrate p,p+,n+,n-. respectively...
p+ substrate is called injection layer because it injects
holes into n- layer .n- layer is called drift region .
thickness of the n- layer determines the voltage blocking
capability of IGBT.
the p layer is called body of the IGBT.
WHERE IT IS USED : it is widely used in medium power
application such as DC and AC motors drives.
UPS SYSTEMS , RELAYS AND CONTACTORS.
In thyristor the gate is triggered the gate is losses its
control. ie if we remove the gate pulse after the thyristor
starts conducting it will not stop.
but in IGBT we can control the Gate. by applying reverse
voltage applied across it .
The Thyristors can not be switched beyond 1kHz where as
IGBTs can be switched upto 25kHz and even to 100KHz with
few soft switching techniques.
The thyristor can carry very high currents order of 3000A
but IGBT carries less current max of 1000A.
Thyristor commutation ,that is switching off is very
difficult. But there are applications of Thyristor with
natural commutation.
The IGBT can be switched on and off like a MOSFET. ie it is
voltage controlled device.
What else can I help you with?
Why IGBT is better?
IGBT first of all is a hybrid device meaning the combination of two devices; the BJT and the MOSFET. Depending on the application, one can never say an IGBT is better than others. Typically, an IGBT is ideal for high powered, high voltage and high frequency applications

What is a Protection device for a semiconductor like a IGBT or thyristor?
There are times when you just can not really protect some devices. IGBT's are serious power devices. Circuitry can sense over currents, but possibly not fast enough to save an IGBT. Over sizing them is probably your best bet.
What is the difference between a single and a dual IGBT?
Single means there is just one. Dual means there are two IGBT's (Insulated Gate Bipolar Transistor) inside the one package.
What are the current trends for power electronics?
Renewable Energy and IGBT Inverters
Is IGBT the bipolar device?
IGBT and BJT are bipolar devices as the name suggest. Meaning of bipolar device both electrons and holes leads to current unlike FET where either electron or hole causes current.
How matrix converter evolved?
At first, there was cycloconverter with thyristors, then matrix converter with IGBT...
