SCR Gate Triggering Circuits
For proper operation of circuits using SCRs, the trigger circuits should supply the firing signal at precisely the correct
SCR Turn Off Commutation Circuits
If an SCR is forward-biased and a gate signal is applied, the device turns on. However, once the anode current IA is above the holding current,
SCR Ratings
The ratings of a semiconductor device give the values for the various conditions that a manufacturer recommends for reliable operation of the device. The use of a device beyond the limits defined by its ratings usually leads to destruction. Therefore,…
SCR in Series
The forward blocking capability of SCRs can be increased when the input voltage exceeds the rating of a single SCR by connecting multiple SCRs in series
Three Phase motor control using SCR
In this method the speed of squirrel cage induction motor control by varying the stator voltage, which is possible
Silicon Controlled Rectifier – SCR
The SCR stand for Silicon Controlled Rectifier, it is used in industries because it can handle high values of current and voltage.
SCR DC Motor control
The speed of DC motor can be control by using SCR in AC circuit as shown in the below figure.
LASCR – Light Activated Silicon Controlled Rectifier
The LASCR is triggered into the Conduction state when the light falls on it, the operation of LASCR is similar
SCR Gate Parameter
There are six important gate parameters, classified in terms of current and voltage. The following four are maximum gate parameters.
