Assertion (A): In a half-wave rectifier with R-L load and with freewheeling diode, the input Volt-Ampere demand is less.
Reason (R): With freewheeling diode, the stored energy is in the load itself.
Explanation:
To understand the given assertion and reason, let's first discuss the operation of a half-wave rectifier with an R-L load and a freewheeling diode.
- A half-wave rectifier is a rectification circuit that converts the positive half cycles of the input AC signal into DC output.
- It consists of a diode connected in series with the load resistor (R) and inductor (L).
- During the positive half cycle of the input AC signal, the diode conducts and allows the current to flow through the load.
- The diode acts as a rectifier and converts the AC voltage into DC voltage across the load.
- During the negative half cycle of the input AC signal, the diode blocks the current flow due to its reverse bias condition.
- In this situation, the freewheeling diode comes into play.
- The freewheeling diode is connected in parallel with the load and allows the current to flow through it during the negative half cycle.
- It provides a path for the inductor current to circulate, reducing the voltage stress across the diode and protecting it from reverse breakdown.
- The energy stored in the inductor during the positive half cycle is discharged through the freewheeling diode during the negative half cycle.
- This energy transfer reduces the input Volt-Ampere demand of the rectifier.
Now, let's analyze the given assertion and reason:
Assertion (A): In a half-wave rectifier with R-L load and with freewheeling diode, the input Volt-Ampere demand is less.
This statement is true. The presence of a freewheeling diode in the half-wave rectifier reduces the input Volt-Ampere demand. The freewheeling diode provides a path for the inductor current to flow during the negative half cycle, reducing the voltage stress on the diode and overall power demand from the input source.
Reason (R): With freewheeling diode, the stored energy is in the load itself.
This statement is also true. The energy stored in the inductor during the positive half cycle is transferred to the load during the negative half cycle through the freewheeling diode. This means that the energy is stored and utilized within the load itself, reducing the demand for energy from the input source.
Conclusion:
Both the assertion and reason are true, and the reason correctly explains the assertion. The presence of a freewheeling diode in a half-wave rectifier with an R-L load reduces the input Volt-Ampere demand, as the stored energy is transferred and utilized within the load itself.
Reason (R): With freewheeling diode, the stored energy is in the load itself.
