ATT Test 8
What are five components of a strength supply?
Input, rectifier, filter, regulator, protection
Which parts of a strength supply are non-obligatory?
Regulator and safety
What is the motive of a energy supply?
To convert AC strength into easy DC energy
What does the enter of a electricity deliver do?
Step up or down the AC enter voltage
What does the rectifier do in a strength deliver?
Changes AC into pulsating DC
What does the filter do in a power deliver?
Changes pulsating DC into smooth DC
How type of components do filters use?
Reactive additives
What does a regulator do in a electricity supply?
Keeps the output voltage at a consistent level no matter adjustments in load current
What does the protection circuit do in electricity supply?
Prevents damage to electricity deliver if load turns into defective, limits or disables output
The half of wave rectifier is the same as what circuit?
Series limiter
Which rectifier is the least efficient the usage of best half the enter?
Half-wave
, Which rectifiers require two input indicators one hundred eighty degrees out of segment?
Full-wave and bridge
Which rectifier makes use of a middle tapped transformer?
Full wave
How is frequency decided for half wave rectifier?
Output frequency is same as input frequency
How is frequency decided for complete wave rectifier?
Output is twice the input frequency
How is frequency decided for bridge rectifier?
Output is twice the input frequency
What is the purpose of collection voltage regulators?
To adjust voltage drop to preserve V out at constant degree
In a chain voltage regulator, V out INCREASES whilst what happens?
Load present day decreases OR DC input will increase
In series voltage regulator, V out DECREASES when what occurs?
Load contemporary will increase OR DC input decreases
If load present day decreases or DC enter increases, what wishes to be completed to
preserve regular degree of V out (collection volt regulator)?
Increase R1 resistance to growth voltage drop on R1
If load current will increase or DC enter decreases, what wishes to be accomplished to
preserve consistent level of V out (series voltage regulator)?
Increase R1 resistance to decreases voltage drop on R1
What is the purpose of parallel voltage regulator?
Adjust current float to preserve V out at steady level
