HC Verma Chapter 45 Problem 11

Problem Statement

In a full-wave rectifier with 50 Hz input, find the ripple frequency.

Key Concepts

Full-wave rectification

Relevant Formulas

f_ripple = 2*f_in

Step-by-Step Solution

Both half-cycles used: two pulses per cycle. f_ripple = 2 x 50 = 100 Hz.

Final Answer

Ripple frequency = 100 Hz

Tips and Tricks

Full-wave is more efficient (81.2%) than half-wave.

Common Mistakes

Always use SI units. Check energy conservation accounts for all forms.
