Question

Explain ripple in the output of a rectifier. What is ripple factor?​

Answer 1

The ripple at the rectifier exit and the description of the ripple factor states that are:

• The unwanted AC components present in the DC feed come out of a filter outlet called Ripple.
• A rectifier is an electrical or electronic circuit that converts alternating current into a direct current.
• The reset circuit cannot provide pure DC supply, other unwanted AC components are also present.
• Ripple Factor is the average rms value of an ace component present in a fixed output to the average rated output value.

• It is a positive value and is defined by γ.
• Its value is always less than unity.

Answer 2

Answer:

The RMS value of an alternating current component in the rectified output divided by the rectified output's average value. The ripple factor is represented by the symbol γ. It is a dimensionless quantity with a value less than unity at all times.

Explanation:

• In rectified DC output, ripple is the oscillating AC component. A rectifier's output might be either DC current or voltage. As a result, the AC fluctuation component present in DC output voltage is known as voltage ripple, and the AC fluctuating component present in DC current output is known as current ripple.
• The term "rectifier" refers to a device that transforms alternating electricity to direct current. Because current can only flow in one direction, a p-n junction can be utilised as a rectifier.
• A p-n junction can be used as a rectifier because it permits current in one direction only.
