Nature of Load Current in Controlled Rectifiers
Type of Load and Firing Angle
The nature of load current in controlled rectifiers depends on two parameters: the type of load and the firing angle.
Continuous or Discontinuous
The load current can be either continuous or discontinuous depending on the above-mentioned parameters.
Continuous Current
When the load is resistive or inductive and the firing angle is less than 90 degrees, the load current is continuous.
Discontinuous Current
When the load is capacitive or the firing angle is greater than 90 degrees, the load current is discontinuous.
Explanation
The reason behind this behavior lies in the basic principle of controlled rectifiers. Controlled rectifiers use thyristors as switching devices to control the flow of current from the AC source to the load.
When the thyristor is turned on, the current flows through the load. When it is turned off, the current stops flowing. This switching phenomenon creates a ripple in the load current.
In the case of a resistive or inductive load, the current flows continuously even when the thyristor is turned off. Hence, the load current is continuous.
In the case of a capacitive load or when the firing angle is greater than 90 degrees, the current flows only when the thyristor is turned on. Hence, the load current is discontinuous.
Conclusion
In conclusion, the nature of the load current in controlled rectifiers depends on the type of load and the firing angle. The load current can be either continuous or discontinuous depending on these parameters.
