A TRIAC or TRIode for Alternating Current is a three-terminal bidirectional thyristor, meaning that can conduct current in both directions when activated properly. It is used in AC switching applications.…
A surge protection device (SPD) or simply a surge protector is a device used to ensure protection against transient surges. It is used to protect the household and commercial applications…
Thyristors are high-speed semiconductor switching devices that are made up of four layers of alternating p and n-type materials. They are used in AC/DC switching and AC power control applications.…
Silicon Controlled Rectifier (SCR) is the first thyristor ever developed (in late 1957). It led to tremendous advancements in power semiconductor devices. They are also known as phase control thyristors.…
Transformers are the most efficient electric machine. A typical transformer is over 99% efficient. The small inefficiency is due to copper losses, core losses-hysteresis and eddy currents losses, stray and…
Several operating indications can be seen on the front of an ACB or MCCB. Being an electrician or an engineer it is important that one must understand those indication and…
An insulated-gate bipolar transistor (IGBT) is a type of bipolar transistor that has an insulated gate terminal. The structure of the IGBT includes an input MOSFET which consists of the…
The common emitter circuit is probably the most widely used transistor configuration. The emitter electrode is common to both input and output circuits. The common emitter amplifier has a typical…
BJT and MOSFET are two types of semiconductor transistors. Even though both of them are transistors, they are different from each other in various aspects. By the end of this…
A Metal Oxide Semiconductor Field effect transistors, commonly known as MOSFET, are semiconductor switching devices that have three terminals which are the gate, drain and source. They are unipolar transistors,…
