Comment on the experimentally measured peak voltage output v

Comment on the experimentally measured peak voltage output values between the half wave, full wave, and bridge rectifier circuits. THINK ABOUT THE DIODE DROP.

Peak Input

Peak Output

Half Wave Rectified

12v

11.2v

Full Wave Rectified

12v

11.2v

Bridge Rectified

12v

10.6v

Solution

1).In half wave rectifier only one diode used...so the droop of diode = input - output

= 12 - 11.2

= 0.8 V

2).In fullwave rectifier even used 2 diodes only one diode conducts for each cycle...

.so the droop of diode = input - output

= 12 - 11.2

= 0.8 V

3).for fullwave bridge rectifier two diodes conducts for each cycle of operation..

so droop of two diodes = 12 - 10.6

= 1.4

so droop of one diode = 1.4/2   

= 0.7
