Understanding SMPS

As all we know that,SMPS is one of the important part of any computer system and after that only very few people know about it.An SMPS(Switched Mode Power Supply) is an electronic power unit that is used as a switching regulator.The main task of any SMPS is to switch the power supply between the saturation (full on) and cutoff (completely off) with a variable duty cycle whose average is the desired output voltage.After this the resulting rectangular waveform that is formed passed through a combination of a capacitor and inductor.The main advantage of this method is greater efficiency because the switching transistor dissipates little power in the saturated state and the off state compared to the semi conducting state (active region).In addition to these advantages,SMPS is light in weight and in smaller size so that it can easily fit into your pc.On the other hand it also have some disadvantages like greater complexity, the generation of high amplitude, high frequency energy that the low-pass filter must block to avoid EMI and a ripple voltage at the switching frequency and the harmonic frequencies thereof.

SMPS can be classified into four types according to the input and output waveforms, as follows.

AC in, DC out: rectifier, off-line converter input stage.
DC in, DC out: voltage converter, or current converter, or DC to DC converter
AC in, AC out: frequency changer, cycloconverter
DC in, AC out: inverter
AC and DC are abbreviations for alternating current and direct current.

Make Your Own Radio Station

Hello friends in this post i am going to tell you the trick with the help of which you can make your own radio station.For this you have to follow these steps:

1.)Must HAVE Winamp (Any Version)
a.)First, things First your speed has to be at least 256/64 kbps (which means Dial-up users, will have alot of latency, just don't bother)
b.)Second, your going to have to have a domain, an updated one with the current i.p active.

Now, Your gonna have to download the Shoutcast Files.
Go to www.shoutcast.com to get the files.
Ok After downloading these, installing Both of them in any order it doesn't matter. Go to START>PROGRAM FILES>SHOUTcast DNAS>EDIT SHOUTCAST DNS CONFIG.

Ok your gonna have to Configure it:
Go Down and where it says password: change (that means your gonna have to change it to whatever, make sure u remember)
The Portbase: change it to whatever port you want it
Maxusers: (lets be realistic here, dnt put in 10000, like NXS's radio station) your bandwidth has to be extremely good, if your cable, 50 user max is ok, ADSL should stay below 10 users, and T1 connections should do whatever tickles there fantasy.

Open winamp, RIGHT CLICK>OPTIONS>PREFRENCES>DSP EFFECT> and choose the NULLSOFT SHOUTCAST.

Go to OUTPUT, and then click on Connection, Through the ADDRESS, type your address which you have done through www.no-ip.com, PORT NUMBER, whatever u did in the EDIT.txt, and your password.

Then go to Encoder, and choose your quality of your music. Go back to OUTPU>OUTPUT CONFIG> YELLOW PAGES. this is your advertisemant information. dow hatever you like there.

Now Connect. to check that your Radio os on-line go to http://(your address that you added in the prefrence).

It is quite simple and still if you have any doubt then post me a comment.
