The VI characteristics of IGBT is as shown in Figure. In the forward direction, they are similar to those of bipolar transistors. The only difference here is that the controlling parameter is the gate to source voltage Vgs and the parameter being controlled is the drain current. The working principle of IGBT is based on […]

Here are the basic electronics tutorial circuits for beginners. You can find here tutorials on operational amplifiers (opamp), transistor, MOSFETs, 555 timer IC, audio amplifiers and many more.
IGBT-Insulated Gate Bipolar Transistor its Working and Applications
An insulated-gate bipolar transistor (IGBT) is a three-terminal semiconductor device it is a hybrid of MOSFET and BJT for high efficiency and fast switching. The power BJT has the advantage of low on state power dissipation, but it cannot be switched at faster rates due to longer turn-off time, whereas MOSFETs have a very high […]
Triac Working, Structure, VI Characteristic and Application
A Triac is a bidirectional device it allows current to flow in both the directions. here we will discuss Triac working and vi characteristics, In the SCR family, after the SCR, Triac is the most widely used device for power control. Triac is a three-terminal device, with the terminals named as main terminals 1, 2 […]
Diac Symbol, Construction and VI Characteristics
The diac is basically a two-terminal device. Here we will discuss the Symbol of Diac and it’s VI characteristics. It is such a combination of semiconductor layers that allows triggering in both directions. The diac is used as a triggering device for the TRIAC circuits. Here we will discuss the Symbol of Diac and it’s […]
SCR as a Switch, its Advantages, Disadvantages and Applications
The SCR has only two states of operation i.e. it can be either fully ON or completely OFF hence SCR can as a switch. There is no “active” region of operation like a transistor.
VI Characteristics of SCR (Silicon controlled rectifier)
The VI characteristics of SCR (silicon-controlled rectifier) is a graph of anode current Ia on the y-axis and anode to cathode voltage on the x-axis as shown in the graph. The characteristics in the reverse direction (anode to cathode voltage negative) is similar to a reverse-biased diode. SCR is a member of the thyristor family. […]
