Rectifiers & Filters
In the block diagram of simple rectifier circuit, from a variable a.c. voltage, constant d.c. voltage is obtained. The correct order of operation is
Show answer and solution
Answer: (c)
- First the diode rectifier turns a.c. into pulsating d.c.
- Then the filter removes the a.c. ripple.
- Finally the voltage regulator keeps the d.c. output constant.
- So the answer is (c) diode rectifier, filter, voltage regulator.
