Explanation:
The minimum value of anode current below which it must fall to completely turn-off the device is called the holding current value. It is an important parameter for the proper functioning of the thyristor device. The holding current is the minimum value of anode current that must be maintained to keep the device in the ON state.
Importance of Holding Current:
The holding current is important because if the anode current falls below this value, the device will turn off completely. It means that the device will not conduct even if the gate signal is present. The device will remain in the off state until the anode current is increased above the holding current value.
Relation between Holding Current and Latching Current:
The holding current value is always less than the latching current value of a thyristor device. The latching current is the minimum value of anode current that is required to turn on the thyristor device. Once the device is turned on, the holding current is required to maintain the device in the ON state.
Effect of Temperature on Holding Current:
The holding current is affected by the temperature of the device. As the temperature increases, the holding current value decreases. Therefore, it is important to specify the holding current value at a particular temperature.
Conclusion:
In conclusion, the holding current value is an important parameter for the proper functioning of the thyristor device. It is the minimum value of anode current that must be maintained to keep the device in the ON state. The holding current is always less than the latching current value and is affected by the temperature of the device.
