A single-phase half-wave rectifier is popularly known as one-pulse converter because for one cycle of supply voltage, there is one half-cycle of output, or load voltage. Hence, both assertion and reason are true but reason is not the correct explanation of assertion.

A single-phase half-wave rectifier circuit is popularly known as one-pulse rectifier.
A single-phase half-wave rectifier is a widely used circuit in power electronics. It is called a half-wave rectifier because it rectifies only one-half of the input waveform. In this circuit, the input alternating current (AC) is converted into direct current (DC) by allowing only one half of the input waveform to pass through while blocking the other half.
A single-phase half-wave rectifier circuit is used to convert AC power to DC.
The primary purpose of a single-phase half-wave rectifier circuit is to convert AC power to DC power. AC power is characterized by a continuously changing polarity, which means the current periodically reverses direction. On the other hand, DC power has a constant polarity and flows in only one direction. By rectifying the AC power, we can obtain a pulsating DC waveform in which the current flows in the same direction.
Explanation:
Both the assertion (A) and the reason (R) are true, but the reason does not provide the correct explanation for the assertion. Let's break down each statement separately.
A: A single-phase half-wave rectifier circuit is popularly known as one-pulse rectifier.
This statement is true. A single-phase half-wave rectifier circuit is commonly referred to as a one-pulse rectifier because it allows only one pulse (half of the AC waveform) to pass through while blocking the other pulse.
R: A single-phase half-wave rectifier circuit is used to convert AC power to DC.
This statement is also true. The primary purpose of a single-phase half-wave rectifier circuit is to convert AC power to DC power. It achieves this by allowing only the positive (or negative, depending on the diode configuration) half of the AC waveform to pass through while blocking the negative (or positive) half. This results in a pulsating DC waveform with a frequency equal to the input AC frequency.
However, the reason does not provide an accurate explanation for the assertion. The term "one-pulse rectifier" refers to the fact that only one half of the AC waveform is rectified, not to the conversion of AC power to DC power. Therefore, while both statements are true, they are not directly related to each other.
In conclusion, the correct answer is option 'B' - Both A and R are true, but R is not the correct explanation of A.
