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.

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 igbt work?
The IGBT combines the simple gate-drive characteristics of the MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors by combining an isolated gate FET for the control input, and a bipolar power transistor as a switch, in a single device. The IGBT is used in medium- to high-power applications such as switched-mode power supply, traction motorinduction heating. Large IGBT modules typically consist of many devices in parallel and can have very high current handling capabilities in the order of hundreds of amperes with blocking voltages of 6000 V control and
Inductioncooker igbt H2OR1202?
yes
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
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
Why IGBT is a voltage control device?
Yes
Is IGBT the bipolar device?

What is the full form of IGBT?
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 is the difference between semiconductor fuse and high rupturing capacity fuse?
Devices such as transistors, IGBT, thyristors in order to protect them the rupture time is in msec. HRC fuses rupture time is more and the current for rupturing is also high making it suitable for motors/resistive loads.
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.
