Troubleshooting Techniques10:30

Electronic Troubleshooting Techniques

Objective: Identify and follow proper procedures when troubleshooting electronic circuits.

Introduction: Examining problems and following a procedure to solve that problem is what we call troubleshooting. It involves first, discovering the cause, second correcting the cause, third correcting the problem. If Only the problem is corrected, but the cause is not discovered and fixed, the problem may occur again. When dealing with electronic circuits and devices the following is recommended:

1-Verify the power connections.

2-Give detailed visual inspections.

3-Monitor the operating electrical parameters.

4-Determine if the circuit has ever worked or if is the first time in operation.

5-Refer to other sources such as manuals, a working circuit or device, and maybe to other technical persons that have worked with the circuits.

Electrical Sources8:34

Introduction: Electrical energy can be harvested from various sources. Some of the common sources of electrical power are:

1-Chemical sources such as the batteries.Batteries rely on chemical reaction to produce voltage. 2-Natural sources such as wind and water, solar, and heat. Wind, Water, Solar and Thermal are other forms of Electrical Power Generation.

3-In the case of the natural sources they need to be converted via a generator in the case of the wind and water.Rectification is the process of: *Converting AC to DC, -Converting DC to AC, -Maintaining a constant voltage output.

4- A solar photovoltaic (PV) in the case of the sun radiation.A solar PV converts solar energy by: -Electromagnetic induction, -Regulation, -Photovoltaic action.
5- A thermal converting devices in the case of heat. Example a boiler heating water to produce steam.
Lecture 5 Electrical Sources
Power Sources and Circuits12:09

•Introduction: The basic electrical circuit is made of 3 elements. Complex circuits are made of these three elements.

•1-Power source.

•2- Electrical conductors.

•3-Electrical load or resistance.

•In all circuits the Ampere-Hour Rating is an important consideration. Kilowatt-Hour is the measure of energy consumption.
Battery Ratings Examples:

A battery rated at 200 mAh can supply current at 5 mA for: -*-40 hours.

200 mAh divided by 5mA = 40 hours

200 mAh divided by 10 mA = 20 hours

200 mAh divided by 20 mA = 10 hours

A battery rated at 50 Ah must last for 5 days. What current can be drawn from it? *-10 Ah per day or .417 Ah.

50 Ah divided by 5 days = 10 Ah per day- OR- 50Ah divided 120 hour = 0.417 Ah

50 Ah divided by 10 days = 5Ah per day –OR-50Ah divided by 240 hour = 0.208 Ah

AC Power Sources19:01

•Introduction: In the study of Alternating Current it is important to Identify the forms of AC signal generation.

•The two basic sources of AC power are electromagnetic sine waves created by:

•1-Electromagnetic AC generators

•2- Electronic equipment such as frequency generators and oscillators.

•Three important elements studied under AC power signals:

•A- Frequency.

•B- Amplitude.

•C-Period

Frequency definition: How many times in a given period the frequency oscillates. F (Hertz) = 1/t(Seconds)

Consider the following F calculations:

a)What is the frequency of a signal that oscillates every

100 milliseconds?

F= 1/t , F = 1/0.100 seconds = 10 Hertz (10 Hz)

b) What happens if the time of oscillation is reduce to 50

Milliseconds?

F=1/t, F = 1/0.010 seconds = 100 Hz…the frequency increases or doubles

c) What happens if the time is double from the original?

F= 1/t, F=1/0.200 seconds = 5 Hz…the frequency reduces.

Frequency and Time are inversely proportional.

Period definition: The time required for the completion of one cycle. Also the reciprocal of the frequency:

T (seconds) = 1/f(Hertz)

Consider the following Period calculations:

a)What is the Time or period of a signal that

with a frequency of 60 Hz per second?

T = 1/f = 1/60 Hz = 0.017 seconds or 17.7 milliseconds

b) What happens if the frequency of oscillation is reduced to 30 Hz?

T = 1/f = 1/30 Hz = 0.033 seconds or 33.3 milliseconds…the time increases or doubles.

c) What happens if the frequency is doubled from the original?

T = 1/120 Hz = 0.008 seconds or 8 milliseconds….time reduces.
Time and Frequency are inversely proportional.

Amplitude definition: How much voltage the signal carries and it is given in RMS (Root Mean Square), either in Peak-to-Peak or just Positive Peak or Negative Peak.

Vrms = Vpx0.707

Vp = 1.414Vrms

Vpp = 2.828Vrms

Consider the following Amplitude calculations:

a)If the Vp = 2 volts, what is the Vrms value?

Vrms = Vpx0.707 = 1.414rms

b) If the Vrms = 1.414, what is the Vp value?

Vp = 1.414 x 1.414 = 2.828Vp

c) What is the Vpp value if Vrms is 1 volt?

Vpp = 2.828x1Vrms = 2.828
Vrms is the voltage value required by a AC source to do the same work of an DC source can do.

-One revolution of the loop generates one cycle of the wave voltage. True

-A four-pole generator has 2 south poles and 2 north poles. True

-An electronic circuit that produces repetitive waves is called: *-Oscillator

-AC generators are called: *-Alternators

-Frequency in a generator is directly proportional to: *-Rate of rotation

F = pole pair times number of revolutions per minutes.
Lecture 7 AC Power Sources
Principles and Properties of AC signals11:59

Properties of AC Signals

1-Harmonic and AC signals:

Harmonics are signals that result from combining two or more AC signals.

2-Polarity of sine wave: Sine waves have Amplitude as discussed previously, but they also have Positive and Negative polarity, Also called Positive Peak and Negative Peak respectively. Polarity changes at the zero value of the sine. Both voltage and current have positive and negative polarity.

3-Period of a sine wave: Period or Time of an AC signal is defined as the Time needed for a single or complete wave cycle. The symbol for time is T.

4-Frequency of a sine wave: Frequency of an AC signals is the number of times the sine wave is repeated within a given period of time or 1 second.
5-Relationship of Frequency and period: Time and Frequency are inversely related, as the frequency increases, the time decreases and vice versa.

Examples Calculations:

If the Period (time) for this sine wave is 2 seconds. What is the frequency of the signal?

F = 1/t = 1/2 S = 0.5 Hertz

If the frequency is 2 Hz, what is the Period?

T = 1/f = 1/ 2Hz = .5 seconds = 500 mS
