A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.
What is the function of a power supply?
A power supply is a device that converts one voltage to another more convenient voltage while delivering power. Power supplies are designed from the output back to the input.
What is a power supply simple definition?
Definition of power supply
: a device providing power to electronic equipment and sometimes designated A, B, or C according to its function of heating vacuum tube cathodes, causing a flow of electron current in plate circuits, or applying a direct voltage in grid circuits.
What are the 3 types of power supply?
There are three subsets of regulated power supplies: linear, switched, and battery-based. Of the three basic regulated power supply designs, linear is the least complicated system, but switched and battery power have their advantages.
What are the 4 stages of power supply?
Power Supplies
- Transformer – steps down high voltage AC mains to low voltage AC.
- Rectifier – converts AC to DC, but the DC output is varying.
- Smoothing – smooths the DC from varying greatly to a small ripple.
- Regulator – eliminates ripple by setting DC output to a fixed voltage.
What are the two types of power supply?
Two types of power supplies exist, DC-DC and AC-DC. DC-DC power supplies allow you to plug in electrical devices into car outlets or similar sources that supply direct current, or DC, power.
What are the types of computer power supply?
Types of PSUs (Form Factors)
- ATX.
- ATX12V.
- SFF (Small Form Factor)
- EPS12V.
- SATA Power.
- 4/8 PIN CPU.
- 6/8 PIN GPU.
- 24 Pin Motherboards.
What are the main components of power supply?
A power supply is an electronic circuit that converts the voltage of an alternating current (AC) into a direct current (DC) voltage. It is basically consisting of the following elements: transformer, rectifier, filter and regulator circuits.
How do you make a 5V power supply?
Step by step method to design 5V DC power supply
- Step 1: The selection of regulator IC.
- Step 2: The selection of transformer.
- Step 3: The selection of diodes for the bridge.
- Step 4: The Selection of smoothing capacitor and calculations.
- Step 5: Making the power supply safe.
What is the difference between SMPS and UPS?
SMPS is a switched-mode power supply which converts AC power into DC power. UPS is a uninterrupted Power supply which could store some amount of energy into it and this energy is used when mains supply in OFF. SMPS do not store the energy.
Is battery a power supply?
Power supply source is any source or device which supplies power and energy to a circuit or system. These include battery, fuel cells, charged capacitor (though short time), generator, etc.
What purpose does a power supply serve in an electronic circuit?
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.
What is an example of a power supply?
A power supply provides components with electric power. The term usually pertains to devices integrated within the component being powered. For example, computer power supplies convert AC current to DC current and are generally located at the rear of the computer case, along with at least one fan.
How power supply works in a computer?
The desktop computer power supply converts the alternating current (AC) from a wall socket of mains electricity to a low-voltage direct current (DC) to operate the motherboard, processor and peripheral devices.A power supply rail or voltage rail refers to a single voltage provided by a PSU.
Which circuit is mostly used in electronics power supplies?
Diode rectifier circuits are used in many areas from mains power supplies to radio frequency demodulation. The diode rectifier circuits use the capability of the diode to only pass current in one direction. There are several varieties from half wave to full wave, bridge rectifiers, peak detectors and more.
How do I choose the right power supply for my electronics?
Power Supply Voltage
If your device needs 9V, you need a 9V power supply. If your device needs 5V, you need a 5V supply. Also, if your device needs a DC voltage (which is the most common), you need a DC output from your power supply. If your device needs AC voltage, you need an AC output.
What is the difference between AT and ATX power supply?
The power switch of AT style power supplies is integrated directly into the power supply itself. This is a physical switch that turns the power supply on and off. ATX style power supplies use a “soft switch” that is controlled by the motherboard.
Which type of power supply is the most commonly used in computer?
The most frequently used power connector is the 4-pin Molex connector. It’s used for a variety of components including older HDDs, optical drives, fans, and certain other devices. Newer SATA components have their own SATA power connector, and you can also use Molex to SATA adapters if you run out of either.
What is the biggest power supply for a PC?
In what’s presumably the world’s largest, most powerful PSU to call an ATX case home, the 2000-watt Modular X3 comes in at 10.25-inches in length and will reportedly fit “wherever a PC Power & Cooling 1000-watt version will”.
What is the best power supply for PC?
