Question
Download Solution PDFFind the latching current of an SCR if the value of the holding current is 21 mA.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- Latching Current: It is the minimum anode current required to maintain the thyristor in the ON state immediately after a thyristor has been turned on and the gate signal has been removed.
- Holding Current: It is the minimum anode current to maintain the thyristor in the on-state.
- Latching current is always greater than holding current.
Application:
Given that, holding current = 21 mA
Latching current should be more than 21 mA
