Advantages of SCR It has no moving parts consequently it gives noiseless operation at HF. The switching speed Is very high. It gives trouble free service because of small size. It permits control over...
CONSTRUCTION OF MOSFET: Metal oxide semiconductor field effect transistor. Gate is insulated from a thin layer of SiO2 , It can be operated in depletion and enhancement modes. MOSFET Is a semiconductor device and...
STRUCTURE OF JFET A junction field effect transistor (JFET) is a three terminal . Semiconductor device in which current conduction is by one type of carrier. I.e, electrons or holes. In a JFET, the...
SCR TRIAC It is unidirectional ie, it can conduct current in forward direction only. It is bidirectional ie, it can conduct current in forward as well as reverse direction. It is triggered by a...
TRIAC The major drawback of an SCR is that it can conduct current in one direction only ie, SCR is a unidirectional device, it can conduct from anode to cathode only and not from...
Bidirectional Thyristor Diode. The term diac means, Diode that can work on A.C. The diac. is a two terminal device . CONSTRUCTION: The diac is a two terminal device . Which can pass current...
Thyristors basically are multilayer semiconducting devices. They are switching devices .they have two stages of operation. Hence are bistable devices. The Two states are ON state and OFF state. the main advantage of thyristors...
Advantages:A SCR has the following Advantages over a mechanical or electromechanical switch. 1.it has no moving parts consequently it gives noiseless operation at HF. the switching speed Is very hi it gives trouble free...
Hall Effect When a specimen (metal or semicoductor) is placed in a transverse magnetic field and a direct current is passed through it, then an electric field is induced across it edges in the...
