Half Wave Rectifier Basics

Explain the working principle of a half wave rectifier.

• A half wave rectifier converts DC input voltage into AC output voltage.

• A half wave rectifier allows current flow during the negative half cycle and blocks it during the positive half cycle.

• A half wave rectifier converts AC input voltage into pulsating DC output voltage by allowing current flow during the positive half cycle and blocking it during the negative half cycle.

• A half wave rectifier converts AC input voltage into constant DC output voltage.

What is the main function of a half wave rectifier?

• Generate direct current (DC) from direct current (DC)

• Convert direct current (DC) into alternating current (AC)

• Convert alternating current (AC) into direct current (DC)

• Amplify alternating current (AC)

Explain the concept of ripple factor in a half wave rectifier.

• Ripple factor is inversely proportional to the frequency of the input AC signal

• The ripple factor is calculated as the ratio of peak voltage to the average voltage

• The ripple factor in a half wave rectifier is calculated as RF = √(Vrms^2 - Vdc^2) / Vdc, where Vrms is the RMS value of the AC component and Vdc is the DC component of the output voltage.

• Ripple factor is not affected by the load resistance in a half wave rectifier
