What exactly is a power supply ?

Power supply

The power supply circuit converts power that is generated by netapp psu AC (AC) into 750 watt power supply direct current (DC) voltage. It is made up of the following components that include rectifier, transformer regulator and filter circuits.

Basic Components of a Power Supply Unit


The transformer is a static device that transfers electric energy between the main and secondary without altering the frequency. It’s used to increase or lower the AC voltage and to isolate the rest part of an electronic device from the AC power source.

It is the primary of its windings that are connected with the AC voltage source, which produces an alternating current. The secondary winding is connected to an electrical load. Both windings do not physically connected but because of electromagnetic induction based on Faraday’s law, there’s an induction voltage present in the secondary winding.


It is the piece of equipment designed to convert AC power into the pulsing DC. The fundamental rectifier is the diode. The diode is a bidirectional device that functions as a rectifier in the direction of forward. The three main rectifier circuits made of diodes include the half-wave, full wave center-tapped and full-wave bridge types.

Purpose of Grounding Rectifiers

The transformer, isolating it from its primary source. The primary source could be grounded, however your secondary winding will not be because they aren’t connected. The secondary circuit is not connected to any potential. The application of a ground will only give this secondary circuit an indication of voltage.


The filter in the power supply is employed to prevent the ripple effect from being visible within the power output. The filter is intended to convert the pulsating DC generated by rectifier circuits into an acceptable soft DC level. The two most common types of power supply filter comprise the capacitor-based filter (C-filter) and the Resistor Capacitor filter (RC-filter). The C-filter is by far the easiest and most cost-effective filter that is available. In contrast, the RC-filter can be used to minimize the ripple voltage that is generated by the capacitor filter.

Its main function is to block the majority part of the DC component, while reducing any AC portion of the sound. This RC filter is made up of capacitors and resistors. The RC filter is used to filter signals by blocking certain frequencies while by passing other frequencies. Common RC filters include Low-Pass filters as well as High-Pass filters.

Ripple and the Ripple factors

Ripple is an unwanted AC part of the signal following rectifying. Ripple is not desirable since it could cause damage or harm the load. This is the principal reason for filters to be installed in the power supply to stop excessive ripples. The purpose for the filter is to smooth the signal, and to reduce AC component or the variations. The ripple factor is that of the right-angled square root value for the voltage ripple to the value of the DC components at output voltage. It is often expressed in percentages or as a peak-to-peak ratio. The ripple factor is a measure of the effectiveness of a filter that is employed by the circuit.

Voltage Regulators

An electronic voltage regulator has been created to give a stable or well-regulated DC output. It is essential to provide a stable output voltage, so that the load functions efficiently. The output level remains constant regardless of fluctuations in the voltage of the input. The most frequently utilized transistor voltage regulators include a shunt voltage regulator as well as the Shunt voltage regulator.

Series voltage regulator

The series element regulates the quantity of the unregulated input voltage, which is then sent to the output in a controlled output. The output voltage that is regulated is measured by a circuit that gives feedback for the circuit that is a comparator, and is compared with an unregulated reference voltage.

Shunt voltage regulator

The shunt voltage regulator offers regulation by diverting current away from the load in order to control the voltage output.

IC Voltage Regulators

The regulator Integrated Circuit (IC) unit includes the circuitry – reference source, the comparator amplifier, the control device and the overload protection – all contained in the same IC. There are also voltage regulators that can be adjusted that let the user adjust the desired output levels. Additionally, IC regulators come with fixed output levels. They are said to be IC regulators perform better the transistor-based voltage regulators in regards to the stability of the output voltage.

How do you define power supply ? What’s its role?

An electrical appliance that provides electricity to an electrical appliance. The main purpose of power supplies is to convert the electric current coming from sources to the right voltage frequency, current, and voltage to power the load.

What are the 3 kinds of supply power?

There are three main types of power supply circuits that are unregulated (also known as brute force) linear regulated and switching. The fourth kind of circuit for power supplies, is the ripple-regulated is a mix of the “brute force” and “switching” designs, and deserves its own section.

How do I find the power source of the computer?

The power supply unit (PSU) is a device that converts primary AC into low-voltage controlled DC energy for the internal components inside a computer. Modern personal computers use switched-mode power sources. Certain power supplies come with an individual switch to choose the input voltage, while other automatically adjust to the mains voltage.

Modern personal computer power supplies for desktops adhere to ATX specifications. ATX standard, and this covers the form factors and tolerances to voltages. When it is true that an ATX power source is connected to the mains power supply It always supplies five-volt standing (5VSB) power source to ensure the standby functions of the computer as well as certain devices are fed.
