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
How to control the high voltage control in an industry?
Voltage stabilisers are the devices to control voltage. These are of 3 types i.e. VARIAC BASED,IGBT BASED and THERMISTOR TYPE. These are classified according to voltage correction speed i.e. from 70 volt/second to 750 volt/seconds.
How control IGBT in closed loop?
To control an Insulated Gate Bipolar Transistor (IGBT) in a closed loop system, you first need to establish a feedback mechanism that monitors the output parameters, such as voltage or current, depending on the application. This feedback is then processed by a controller—often a PID controller—that compares the measured output to a desired setpoint. The controller adjusts the gate drive signal to the IGBT accordingly, modulating its conduction state to maintain the output at the desired level. Implementing appropriate filters and protection circuits is also important to ensure stable operation and prevent damage to the IGBT.
What is the meaning of voltage control device and current control device y they call like this?
In vcd, input voltage controls the output current.e.g.jfet In ccd , input current controls the output current. e.g. bjt
What is a tachogenerator in control system?
a device to measure rotation speed of a shaft as a proportional voltage

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
Is thyristor a current controlled or voltage control device?
Triac is the current control device.
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.

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 BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
What is the meaning of voltage control device and current control device y they call like this?
In vcd, input voltage controls the output current.e.g.jfet In ccd , input current controls the output current. e.g. bjt
How does a voltage controlled amplifier work?
A Voltage Controlled Amplifier or VCA is a device whose gain is set by the voltage level of a control signal.
What is basic difference between Potential meter and rheostate?
Potential meter is voltage control device and rheostate is current control device. it is a basic difference.
What is a tachogenerator in control system?
a device to measure rotation speed of a shaft as a proportional voltage
