KL- 21001 linear circuit lab
Experiment module: KL- 23002
Experiment instrument: DMM, AMM
Tools: Basic hand tools
Materials: As indicated in the KL-23002
3.3 Procedures
(1) EXPERIMENT FOR HALF-WAVE RECTIFIER
(1) Half- wave rectifier circuit without a filter capacitor
1
First, fix the module KL-23002 in the KL-21001 Linear Circuit Lab, then locates
2
the block marked 23001- block c.
Insert the short-circuit jumper clip by referring to Figure 4.1 and the short-circuit
3
4
clip jumper arrangement diagram in Figure 4.2.
Apply AC source 9V to Vac from AC Supply on KL-21001 Linear Circuit Lab.
Measure V by using ACV scale of Multimeter and Oscilloscope respectively, then
5
record in Table 4-1 (a).
Measure the output terminal (OUT) by using DCV scale of multimeter and
oscilloscope, where in the DC scale of oscilloscope will be used to test Vdc and
the AC scale of oscilloscope will be used to test the ripple.

Then record in Table 4-1(a).
(2) Half- wave rectifier circuit with a filter capacitor.
1
Insert the short-circuit clip jumper by referring to Figure 4.3 and the short-circuit clip
jumper arrangement diagram in Figure 4.4 (C 6 : 220 )
2
Insert the short- circuit clip by referring to Fig 1-2 (a) and the short- circuit clip
arrangement diagram 23001-block a.3(a) (forward connection). Connect the
3
voltmeter and Ammeter.
Connect the +12V, then adjust VR(10K) to apply voltage to 2 terminals of the
diode as shown in Table (3) from 0.1V to 0.7V and view the corresponding If
4
(forward current). Then record in Table (3).
Insert the short- circuit clip by referring to Fig 1-2(a) and short-circuit clip
arrangement diagram 23001-block a.3(b) (reverse connection). Connect the
5
voltmeter and ammeter.
Adjust VR2 (VR10K) to apply reverse voltage to 2 terminals of the diode as
shown in Table (4) from 0V to 5V, and view the corresponding Ir (without

breakdown). Then record in Table (4)
Plot the values of Table (3) (4) on the coordinate paper (Fig 3).
3.4 Results and Analysis
Draw the graphs and do some analysis.
