Advances in Technologies Widen Market Opportunities for SCR Power Controlled Use
Silicon Controlled Rectifiers (SCR) are Thyristors, a three-junction P-N-P-N semiconductor devices treated as two interdependent transistors used in the switching of heavy electrical loads. SCR is a Shockley diode added with an extra terminal called the gate, used for triggering the SCR into conduction. An SCR unit is a combination of two SCRs arranged to control AC power. A solid state switching device provides fast, infinitely variable proportional control of electric power. With its optimum use, the SCR hold ability to switch on and off over a billion times. SCR, is also known as Shockley diode with an extra added terminal called as gate. The SCR power controller has two states, On and Off, allowing unidirectional flow of current. SCR power controllers are modelled to supply electric power to resistive loads. The controllers include power semi-conductors (SCRs), trigger circuitry, fuses supplied on panels and properly-sized heat sinks. SCR power controllers play a vital role in i...
