Basic Electronics Assignment Q&A

The ripple factor is a measure of the effectiveness of a rectifier circuit in smoothing out the AC ripples from the rectified output.

Advantages: better filtering efficiency, lower ripple. Disadvantages: higher cost, larger size.

Step 1: Determine the required output voltage and current. Step 2: Choose a transformer with appropriate secondary voltage. Step 3: Select rectifier and filter components. Step 4: Calculate the ripple factor and choose appropriate filter type.
