Are you curious to know what is holding current? You have come to the right place as I am going to tell you everything about holding current in a very simple explanation. Without further discussion let’s begin to know what is holding current?
Holding current is a term used in electronics to describe the minimum current required to maintain a device in an “on” state. It is an important parameter to consider when working with devices such as thyristors, which are commonly used in power electronics. In this blog post, we will take a closer look at holding current and its significance in the world of electronics.
What Is Holding Current?
Holding current is the minimum current required to maintain a thyristor in an “on” state after it has been triggered. A thyristor is a semiconductor device that is used to control high voltage and current levels. When triggered, it allows current to flow from its anode to its cathode, much like a switch. However, once the trigger signal is removed, the thyristor should switch back to its “off” state and stop the flow of current.
However, in some cases, the thyristor may remain in its “on” state even after the trigger signal has been removed. This is known as latching, and it can cause problems in the circuit, including overloading and damage to the device. Holding current is the minimum current required to keep the thyristor in its “on” state, preventing it from latching.
Why Is Holding Current Important?
Holding current is an important parameter to consider when working with thyristors and other similar devices. If the holding current is too high, it can cause unnecessary power dissipation, which can lead to overheating and failure of the device. On the other hand, if the holding current is too low, it may not be able to keep the device in its “on” state, which can cause latching and other problems.
Holding current is also important when designing circuits that use thyristors. By understanding the holding current of the device, designers can ensure that the circuit is designed to maintain the minimum current required to keep the thyristor in its “on” state. This can help to prevent problems such as latching and overloading, and ensure the reliability and safety of the circuit.
Conclusion
In conclusion, holding current is an important parameter to consider when working with thyristors and other similar devices in electronics. It is the minimum current required to maintain a thyristor in its “on” state after it has been triggered. By understanding the holding current of a device, designers can ensure that circuits are designed to maintain the minimum current required to keep the device in its “on” state. This can help to prevent problems such as latching and overloading, and ensure the reliability and safety of the circuit.
FAQ
What Is Holding Current In Scr?
Holding Current in SCR
Holding current in thyristor or SCR can be defined as, the smallest amount of current under which anode current has to drop to enter OFF status. This means, if the holding current value is 5 mA, subsequently thyristor’s anodes current have to turn into less than 5 mA to discontinue performing.
What Is Meant By Latching Current And Holding Current?
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.
What Is The Value Of Holding Current?
Holding current of SCR or thyrsistor is that minimum value of current below which anode current must fall to come in OFF state. This means if the value of the holding current is 5 mA, then the anode current of SCR must become less than 5 mA to stop conducting.
What Is The Holding Current And Latching Current In The Thyristor?
In a thyristor, Latching current (IL) is the minimum current needed to be attended by SCR to turn it ON. And Holding current IH is the minimum current above which must be continuously flown through it to keep it in an ON state. The Holding current(IH) is always less than the Latching current (IL)in a thyristor.
