Questions:
Q2.1 – Assume a half-wave rectifier is used to supply a DC voltage to a load. Also assume that the AC
source voltage is 24VRMS. How much DC voltage will be applied to the load? (Include the diode drop in
your calculations)
Q2.2 – What effect does an open diode have on the output voltage and frequency of a half-wave rectifier?
And on those of a full-wave rectifier?
Q2.3 – When a 1KHz sinusoidal voltage is applied to the input of
a) a half-wave rectifier, what is the output frequency?
b) a full-wave rectifier , what is the output frequency?
Q2.4- If the amount of filter capacitance in a rectifier circuit is increased, what happens to the following
parameter?
a) Ripple peak-to-peak :
b) Output DC voltage :
c) Voltage drop across diodes
