A full wave rectifier using a diode bridge and a 120V/12V transformer is designed
to deliver power to a 100 load. Assume all diodes have Von=0.7V and negligible
off current.
a. What is the ripple voltage, if the capacitance of the filter is 2500μF?
b. Considering the ripple calculated in part a, what is the average DC voltage of
the output (hint: it will be approximately the peak (max) voltage minus Vr/2)?
c. Considering the average DC voltage of the output found in part b, determine
the average current and power in the load resistor.
Expert Solution
Step 1: State the given data.
Full wave rectifier using a diode bridge,
Transformer rating = 120 V/ 12 V
= 120 V
= 12 V
Load 
= 10
of all diodes = 0.7 V
Capacitance of the filter = 2500 μF
We need to find :
(a) The ripple voltage.
(b) The average DC voltage of the output.
(c) The average current and power in the load resistor.
