Explanation:
power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
11. describe the following power sources.AC Transformer DC Generator Transformer Rectifier
Answer:
An AC transformer is an electrical device that is used to change the voltage in alternating current (AC) electrical circuits. One of the great advantages of AC over DC for electric-power distribution is that it is much easier to step voltage levels up and down with AC than with DC.
A DC generator is an electrical machine whose main function is to convert mechanical energy into electricity. When conductor slashes magnetic flux, an emf will be generated based on the electromagnetic induction principle of Faraday's Laws.
A transformer rectifier is a type of transformer that contains thyristors or diodes within a single tank. It may also include voltage regulation. It is highly beneficial for processes in industries that necessitate a large supply of direct current (DC).

A DC generator creates an electric current that flows in one direction while the currentproduced in an AC generator flows in two direction alternatelyD. A DC generator creates an electric current that flows in a definite direction while the flowof current produced in an AC generator has no definite direction
a DC generator different from an AC generator: A DC generator creates an electric current that flows in a definite direction while the flow
of current produced in an AC generator has no definite direction.
An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction. In an AC generator, the coil through which current flows is fixed and the magnet usually moves.The two backup generators are used for different purposes.
Differences in AC and DC GeneratorsAs a tool that is capable of generating electricity and providing balance in its use, it is also important to know the differences that lie in it. In general, the difference between these two generators is in the rotor and stator aspects.
The first type of difference between AC and DC generators is found in the rotor and stator mechanisms. It is important to know in advance that the rotor is a rotating component in the generator, while the stator is a stationary component during rotation.
For generators in AC machines, the magnetic field will be generated by the rotor. Meanwhile, the function of the stator is to produce a conductor to prepare for acceptance of movement by electrons.
In general, the conclusion is that the generator aspect of the AC function of the magnetic field will rotate in the electric coil. Although in general the magnetic field is generated by permanent magnets, in this generator the AC current comes out because there is a magnetic field in it.
Meanwhile, the DC generator has a mechanism that is generally similar to the AC generator. This similarity occurs because the stator in a DC generator functions as a stationary component while the rotor is a moving component.
In essence, the difference between AC and DC generators is in the magnetic performance. If a permanent magnet functions as a stator while an electric coil functions as a rotor. So that this generator can produce electricity in DC, because the coil will rotate in a magnetic field.

27. product assembly of 5v ac-dc power supply
A 5V AC-DC power supply is a device that converts alternating current (AC) to direct current (DC) and provides a steady 5V output. The assembly process for a 5V AC-DC power supply typically involves several steps:
PCB layout and design: The first step is to design and layout the printed circuit board (PCB) that will hold all the components of the power supply. This includes selecting the appropriate components, such as the transformer, diodes, and capacitors, and arranging them in a way that allows for efficient and safe operation.Component placement: After the PCB is designed, the next step is to place the components onto the PCB. This involves soldering the components in their designated positions, making sure that they are properly aligned and securely attached to the board.Testing and debugging: Once the components are placed, the power supply is tested to ensure that it is operating correctly. Any issues that are discovered, such as a short circuit or incorrect voltage output, are then debugged and corrected.Final assembly: After testing and debugging, the final assembly of the power supply is performed. This includes attaching the input and output connectors, such as the AC plug and DC jack, and any other external components such as a switch or indicator lights.Final testing and quality control: The power supply is tested again to ensure that it meets the specified performance and safety requirements. Quality control measures are taken to ensure that the power supply is free from defects and meets the industry standards.Note that this is a general overview of product assembly of 5V AC-DC power supply and the actual process may vary depending on the manufacturer or specific model.
28. Learning Task 2.1. What is the main function of power supply in your pc? 2. What uses a 12v power supply? 3. Why do computer use DC power instead of using AC power?
Answer:
1. A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
2. Voltage: All of the power supplies we sell are 12V DC. They take any input from 100V up to 220V AC, which is what comes out of your wall socket, and output 12V DC. This is what most digital devices such as LCD screens, DVD players, Hard Drives, Audio Gear, and most other digital devices use.
3. DC is much more easy to control, accurate and easier to propagate than DC signal. If we use AC in most of electronic circuits instead of DC, It will create extra work for just handling the phase-shift between signals. It will be harder to supply them by batteries.
