ANALYSIS AND CONSTRUCTION OF SWITCHING POWER SUPPLY (English)
Abstract [sv]

I dagens samhälle utvecklas tekniken snabbt, allt ska bli mindre och samtidigt ska mer funktioner byggas in. På grund av detta blir stora komponenter som toroidtransformatorer allt mindre önskavärda. Men går det att ändra designen till ett mindre switchat nätaggregat problemfritt?

Denna rapport kommer gå igenom grundläggande teori för att förstå hur ett switchat nätaggregat fungerar, samt beskriva momenten i framtagningen av en prototyp. Rapporten tar även upp moment som beskriver hur mätningar av elektromagnetiska störningar genomförs.

Vi kommer se att jag lyckas ta fram en fungerande prototyp som fungerar inom kravspecifikationen. Dock får man inte ut den sökta verkningsgraden, det finns alltså förbättringsmöjligheter. Men en prototyp är ett av de många stegen till en färdig produkt.

Abstract [en]

same time more functions need to get built in. Because of this is a big component like a torodial transformer is no longer desirable. But is it possible to change the design of a linear power supply to a switch mode power supply without any problems?

This paper presents the basic theories of how switch mode power supplies work, together with a description of how an electronic prototype is developed. An introduction on how electromagnetic interference measurements are done will also be presented. We are going to see that a working prototype can be developed. But the target efficiency is not reached, there is need for improvement. But remember, a prototype is the first step to a finished product.
