Task Description:
A half-wave rectifier is an electrical circuit that converts AC voltage to DC voltage. Figure 1
illustrates a rectifier circuit that consists of an AC voltage source, a diode, a capacitor, and a
esistor as the load. The operation of the rectifier is illustrated in Figure 2 where the dashed
line shows the source voltage, and the solid line shows the voltage across the resistor. In the
first cycle, the diode is in the “on” state and conducts cu
ent from t = 0 until t = tA. The diode
then switches to “off” state and the power to the resistor is supplied by the discharging
capacitor. At t = tB the diode switches to “on” state again and continuous to conduct cu
ent
until t = tD. The cycle continues as long as the voltage source is on.

When the diode is in the “on” state, the resistor’s voltage and cu
ent are given by:

When the diode is in the “off” state, the voltage across the resistor is given by:
0 sin( )
At t RC
Rv v t e
The times when the diode switches off (i.e., tA, tD, and so on) are calculated from the condition
iR = -iC. The diode switches to “on” state again when the source voltage equals to or more than
the voltage across the resistor (i.e., tB in Figure 2).
1. Investigate the outcome of varying ? , ? , ? and ? towards the half-wave rectifier
performance via a MATLAB-based application (i.e., MATLAB App) which should contain
the following features:
(a) User can select one of the five (5) presets of ? , i.e., 10, 15, 20, 25 and 30 V, respectively;
user can also indicate a specific ? but do limit the range of ? to 5 V ≤ ? ≤ 40 V.
(b) User can specify the values of ? and ?; default values of ? = 1800 and ? = 45 F should
e used if no values were specified by the user; avoid negative or zero value entries.
(c) User can specify the values of frequency, f, to be from 50 Hz to 150 Hz; avoid negative or
zero value entries.
(d) Allow user to plot and compare three (3) variations of voltage across the resistor as a
function of time for 0 ≤ t ≤ 100 milliseconds and superimpose the source voltage in the
same graph. with different combination of ? , ?, ? and ? values; clearly label the graphs.
(e) Do include checking and warning routines to prevent user from entering non-valid values
or datatypes.
(f) You may enhance the appearance of the MATLAB App by inserting pictures and changing
the properties of the components contained in the application.
