What is Power Supply?

A power source is an electronic device that provides electrical energy for the operation of different devices. Electrical energy is obtained from primary energy sources and the power source is used to transmit this energy to the desired device at a certain voltage and current level. The electrical power source, which plays an important role in the uninterrupted continuation of daily life, can also be expressed as power supply. All devices that have the responsibility of providing energy, what is the power supply? can be given as an answer to the question.


The part that will ensure the balanced distribution of the electrical energy that will enable the computer equipment to work is the power supply, that is, the power supply. The usage areas of power supplies are quite wide. Power supplies are needed in homes, offices, industrial facilities, hospitals, communication systems and many electronic devices. For example, computers, televisions, mobile phones, tablets, household appliances, electronic systems of vehicles and many other devices cannot work without power sources.

What Does a Power Supply Do?

The main purpose of power supplies is to ensure the smooth and safe operation of electronic devices. Many electronic devices need a certain level of voltage and current to operate, and an appropriate power supply must be used to meet these requirements. In addition, power supplies reduce fluctuations in electronic circuits, allowing devices to operate more stably.


Power supplies ensure stable operation of electronic devices by providing electrical energy at correct voltage and current values. These sources provide the energy needed by the devices by converting the alternating current (AC) from the main power source to direct current (DC).


Another important feature of power supplies is that they have various protection mechanisms. Power supplies, which have the feature of automatically closing the circuit in cases such as overvoltage, overcurrent, overheating, prevent the devices from being damaged and provide a safe working environment.

What are the Power Supply Types?

The ever-increasing energy demand has revealed the types and features of uninterruptible power supplies. Types of power supplies that provide the operation of many devices, especially computers, are important components that provide the energy necessary for the operation of electronic devices. These sources are divided into two main categories as alternating current (AC) and direct current (DC), and AC and DC power supplies have different characteristics and usage areas.


Alternating current (AC power supply) works by using electricity from the electrical grid. AC power supplies, which are widely used in homes and industrial facilities, generally operate at standard voltages such as 220V or 110V. AC power supplies enable electronic devices to operate by regulating a fluctuating current from the electrical network and providing it at the desired voltage and frequency.


Direct current DC power supply, on the other hand, provides electrical energy directly from a source. These sources use DC energy, usually from batteries or accumulators. DC power supplies provide a specific voltage and current value to meet the energy requirements of electronic devices. DC power supplies provide a more stable energy supply and provide a continuous flow of energy to electronic devices. Such sources are widely used in portable electronics, vehicles and solar power systems.

How Does the Power Supply Work?

Power supplies are important for the correct and flawless operation of electronic devices. In this context, for a correct working system, a power supply suitable for the different power requirements of different devices should be selected. In addition, the efficiency, reliability and protection features of power supplies must be considered. So how does the power supply work?


The power supply, which cannot be operated alone, must first receive a working signal from the motherboard. After the power supply is connected to the motherboard, the device is started by pressing the power supply button. Of course, power supplies can have different operating systems in different devices.
