What is SMPS? Its Works, Types and Future Uses

836

Do you know what is SMPS? Everyone uses a computer in today’s world, and it is a desktop or a laptop. There are different parts inside and all those parts need electricity. However, this power is much less than that we use in our house. We can say that it takes less power than TV, FRIDGE, IRON, and OVEN, that we use in our house. If this voltage is given to the computer or SMPS, then it will burn. So how much power will the computer need? let’s be aware of what is SMPS.

What is SMPS

The full name of SMPS is “Switch Mode Power Supply” and is an electronic circuit. If you buy a desktop, you will get some square shape of the SMPS. It gives power to different parts of the device computer such as RAM, Motherboard, Fan etc. By the way, MotherBoard consumes the power and provide it to different degrees.

Now we know a little about its work, so when it first gives the main power supply to the computer from the home board, then it first stays in the form of AC (Alternative CURRENT), and then when the SMPS of the AC computer This converts it to DC, it uses Capacitor and DIODE for this.

With the help of the Regulator, it switches ON and sometimes OFF means Switch Mode changes, sometimes DC to AC CONVERT and sometimes AC to DC, hence its name also called Switch Mode Power Supply The Yota. Now you know what is Switch Mode Power Supply.

How SMPS works – (What is SMPS)

So firstly I come to the current computer from the cable, then it goes through the small device inside the SMPS first, then firstly it goes to the AC filter wherein the process of filtering the AC filter, Neutral and Phases The bitch uses NTC, Fuse, line Filter, PF Capacitor, its output is given to Rectifier and Filter, which converts it from AC to DC which was Rectifier and filter which was with the help of two capacitors Smooth converts to DC.

The output of this process is Pure DC and switching it. There is a lot of G transistor, but here we use two NPN transistor with the help of a switching cycle then gives an AC output. Then we use it to do another process called SM transformer, this is SMPS.

Let’s talk about PRIMARY CIRCUIT. Private Circuit is given once more to the Rectifier and Filter which converts this AC Supply to DC. (remember one thing from the transformer at home The current that comes is AC and the current that comes in the battery is DC). Area after the action occurs in Output turned out that three Form A 12VOLT, 5 VOLT, 3 VOLT. This is the primary and secondary circuit of SMPS.

Primary and secondary circuit of SMPS

But the primary circuit’s Rectifier and Filter connect with an Output Starter transformer and connect with Starter which is connected with an Amplifier IC and has three Output WIRE, the amplifier IC is an area of ​​SMPS where There is complete management work on it.

Amplifier IC has three Major Cable Nickel Tee One is green which is Power on cable, the other one comes in Violet color which gives stand by a current of +5 volt, and the third one is in Gray color, which is called Power Bood cable Said much. All three Output cables are given to MotherBoard.

The switching transistor and amplifier IC are connected with a driver and are controlled through the amplifier IC. From the second switching circuit comes a sensing wire that tells the amplifier IC that the load is increasing, then at the same time DRIVER which increases the SWITCHING Transmitter on-off process, and which gets the voltage at a constant speed.

In this there are + 12volt, + 5volt and + 3volt. This process is called switching mode power supply? 12v, 5v, and 3v SMPS to MotherBoard when the green cable is power on getting to This is how it works.

 

What is Direct Current and Alternative Current


By the way, the current means the Flow of Charge. These are of two types 


1. Direct curren

2. Alternative current

The flow of charge in alternative current is in both directions, here it is in both directions from positive to negative and negative to positive, but if we talk about direct current, then it is only flowing in one decay from negative to positive. A good example of this is the DC current of the battery which you use in your TV and watch.

To understand this a little better, we tell you a very good example. This is the electricity that comes to your house. This is a good example of alternating current. Now the battery that is in the remote is the direct current. If your computer needs to convert the alternating current to DC, then it uses SMPS.

Types of SMPS (What is SMPS)

1. DC to DC Converter 
2. Forward Converter 
3. Flyback Converter 
4. Self-Oscillating Flyback Converter

1. DC to DC Converter


This is the type of an SMPS converter in which all the CURRENT that you have with the SMPS is AC, before converting it to DC, the current that passes through the DC converter first passes through the primary side of the Step-Down Transformer

This step-down transformer is only a part of SMPS which is 50 Hz, it is high in voltage, the second part of the rectified and filter hock transformer, now it is out of the Output Voltage Power to go to different parts. The output of this is send once more to the Switch. To control the voltage.

2. Forward Converter


It is also a converter that takes a lot of current through choke whether the transistor does its job or not. This work is done by diode when the transistor is fully closed. So, for this reason, there is energy excess within the load, it happens during both off and on, but keeps the choke energy, during the ON period and sends some energy to the output load. 


3. Flyback Converter


In this Flyback Converter, Magnetic Field Energy stores the inductor when the switch is on. When the switch is on, the power output is empty in the voltage circuit. Duty Cycle determines the output voltage. This is its job. 


4. Self-Oscillating Flyback Converter


This is the easiest and basic converter that works over Flyback. At the time of conduction, the switching transistor increases linearly from the transfer to a slope which is Vin / Lp.


Types of SMPS according to usage


The type of power supply depends on its size and usage. Its types are AT SMPS, ATx SMPS, Baby SMPS. But AT and ATx are uses the most. What is SMPS? Here SMPS’s full name is Advance Technology SMPS, and ATx SMPS is full name is Advance Technology Extended SMPS.

SMPS Connectors


1. 20 + 4 Pin ATX This is a MotherBoard Connector, this connector gives the charge of MotherBoard +12 Volt. This Connector uses AT SMPS 20 and ATX SMPS 24 Pin. In this, A 24 pin connector and a 24 pin motherboard is used. 


2. CPU4 + 4 Pin Connector This Connector is required for CPU which uses 4 pins which are all of 12v and have a connector named SATA Power Connector


3. SATA Power Connector Computer consists of Hard Disk and DVD ROM, it gives Power Connector Power to them. This was some information about the Power Connector of SMPS. This is a 4 pin connector.


How will SMPS be in the future


But before Going forward, there will be more special SMPS that can convert the voltage to the best and can be done easily. Go ahead and go through these things below.

  • It can provide more output, 
  • can take more voltage and can output less voltage, 
  • increase the reputation of power, 
  • switching mode and work faster.

So friends today, you must have felt very good, I hope you have got this information for you and if you do hardware repair, then you have more benefit, you have already become capable of knowing what is SMPS You can answer this question becasue it has a big contribution in our computer.
