Power Supply

Power Supply Equipment - A power supply is a device that converts one voltage to another more convenient voltage while delivering power. From the output back to the input,  Power supplies are designed. Below we have mentioned the further details about the power supply equipment. 

This equipment is the hardware component that provides the power to an electrical device. It converts the current from AC (alternating current) to DC (direct current), by receiving the power from an electrical outlet which is what the computer requires. to an adequate amount, it also regulates the voltage which allows the computer to run smoothly without overheating. 

By simply finding the input you can locate the power supply on a system unit where the power cord is plugged in. Into a number of sections or building blocks, power supply electronics circuits can be split. To the operation of the power supply, each is important but each section of the power supply electronics is required to perform its function satisfactorily for the successful operation of the whole unit.

A power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters.

Types of electronics power supply

When it comes to a power supply then there are three classifications that can be used. All these have their own advantages and disadvantages and under slightly different circumstances, each is used.

Here are the three major types of electronics power supply are:

• Rectified and smoothed power supply - These electronics power supplies are generally used for non-critical applications and known as the simplest types where performance is not a major issue. In thermionic valve or vacuum tube equipment, this type of power supply was widely used it and often the requirements were not so critical and were not so easy to regulate supplies.

• Linear regulated power supply - This type of electronics power supply is capable to provide a very high level of performance. It can be comparatively inefficient, dissipating a significant proportion of the input power as heat as it uses a series regulator element. Nevertheless, with low values of ripple, etc, these power supplies can offer very high levels of regulation.    

• Switch-mode power supply -  In this form of power supply, electronics circuits use switching technology to regulate the output. Although spikes can be contained in much smaller packages than their linear equivalents, as these are present on the output, they offer very high levels of efficiency.

The basic concept behind voltage regulator circuits

There is distinctive sort of  voltage regulator circuits and integrated circuit regulators, the basic concepts for the circuits fall into one of two basic categories:

• Series regulator circuit

• Parallel or shunt regulator circuit.

Series regulator, is the most common type seen for full voltage regulator circuits is the. All voltage regulator circuits fall into one of these categories.

In addition to voltage regulators being categorized as series and shunt regulators, it is also possible to categorize them into two other categories depending upon the mode of operation:

• Linear voltage regulators.

• Switching voltage regulators.

Each type has its own advantages and disadvantages, all linear and switching regulator circuits are widely used. And therefore a choice of the type of regulator needs to be made dependent upon the application envisaged.

As mentioned above we have provides the details about power supply equipment, as the power supplies devices are an important element in many items of electronics equipment. There are different sorts of equipment some are battery-driven, others need mains power supplies, and the power supply electronics circuitry and design are of paramount importance to the successful operation of the whole equipment. Above you can get into the details and know more in-depth about these power supply devices.
