					<description>Dvi taisyklės:
1. Visas trafas vyniojamas viena kryptimi. Pvz. pasiima trafą tvirtinimu žemyn ir visas apvijas vyniojam pagal laikrodžio rodyklę.
2. Kur svarbu, schemose pažymėtos apvijų pradžios. Pradžia žymima taškeliu arba žvaigždute.</description>

					<description>ok, bro, fine explanation there, thanks, bro

ill see what i can do now, i think i have to dig from beginning, man....

lots of work is gonna needed, i think id ask u more in future man, hope u ok with that. ill try to throw only quality questions tho, no worries, bro</description>

					<description>r00liui: trafo vyniojimas detaliai aprašytas mikroschemos datasheete. Dar apie trafus kiek parašyta čia:
http://www.vabolis.lt/2006/03/22/trafuko-vyniojimas/

for riky: As various parts of the schematics are connected to &quot;live&quot; parts, there is voltage difference in &quot;ground&quot; points up to 450V. So, to keep everybody safe and alive, PSU must be with floating grounds.
About the coil. When coil is in resonant mode, &lt;a href=&quot;http://www.vabolis.lt/2010/06/16/kaitintuvo-oscilograma/&quot;&gt;simple calculation show&lt;/a&gt;, that more than 500A current is runing. Simple copper wire is getting hot in a minute. So, we use copper tube and run water inside. Same problems with resonant capacitors. They became hot and can explode. Serious explosions- it can hurt you.
Component list is in chip datasheet. I insist every reader of my blog to read original documentation before. It is live voltage, it can &lt;font color=&quot;#FF1010&quot;&gt;kill you!&lt;/font&gt;
Also, there is translation problem: sometimes I am using &quot;pulsed PSU&quot;, but real name for this device is &quot;switchmode PSU&quot;. It is simple translation problem. In Lithuanian language it is &quot;impulsinis maitinimo šaltinis&quot; and directed translation could be like &quot;pulsed power suply&quot;.</description>

					<description>THANKS A LOT FOR UR HELP, BRO. I AM UR FAN FOREVER, MAN

and sorry for my noob question, i heard a someone build his induction heater along with the &quot;isolated transformer PSU&quot;. so PSU is a must then, bro ? i meant, what if i use &quot;stavolt&quot; or &quot;pc psu&quot;. and i read someone built his induction heater with a help of oscilator, to test wheter the circuit is good or no.

and this is first time i hear about &quot;pulsed PSU&quot;. thats scary.
can u just give an explanation of how to make simplest complete &quot;ready to use&quot; induction heater, man. i am confused with all the &quot;pulsed psu&quot;, sounds kinda intimidating for newbies, man.

and about ur problem with heating, i saw someone in youtube with copper tubing, i heard its usualy for air conditioning system in houses or fueling pipe in motorbikes. then they run ice water through it to cool it using submerged pump thats usualy for the use of aquarium. 

btw bro, u forgot to attach the components list, man. thanks for ur great help and ur attention to newbie fans like me tho, bro</description>

					<description>This is generic PSU using schematics from Fairchild semiconductors default datasheet. Nothing new. I don't know if it is possible to build this PSU without knowledge of how it works and how to build transformer.

There are several articles in Lithuanian language:
http://www.vabolis.lt/2006/03/22/trafuko-vyniojimas/
http://www.vabolis.lt/2006/03/07/galingo-maitblokio-transformatorius/
http://www.vabolis.lt/2006/03/06/galingas-maitblokis-su-keliais-isejimais-2/
http://www.vabolis.lt/2006/03/05/galingas-maitblokis-su-keliais-isejimais/

Some of these articles are translated into English language:
http://blog.savel.org/2006/03/23/winding-the-transformer/
http://blog.savel.org/2006/03/08/transformer-for-psu/
http://blog.savel.org/2006/03/06/high-power-psu-2/
http://blog.savel.org/2006/03/05/high-power-psu/

And this PSU is not mandatory. It just make my life better and save lots of space in my induction heater box.

Component placement:
&lt;img src='/stuff/20100621a.gif' alt='pcb' /&gt; 

&lt;a href=&quot;/stuff/20100621b.gif&quot;&gt;PCB image (600dpi).&lt;/a&gt;

Image of schematics:
&lt;img src='/stuff/20100621d.gif' alt='' /&gt;
&lt;a href=&quot;/stuff/20100621c.gif&quot;&gt;Image for printing&lt;/a&gt;.
R10 - 4.7K, R11- 12K (as I remmember :) ) 

This new PSU replaced this:
&lt;img src='/stuff/20100621e.jpg' alt='replacement' /&gt; 
There are 3 transformers and one pulsed PSU.

Old PSU in the box:
&lt;img src='/stuff/20100417a.jpg' alt='replacement PSU' /&gt;
And now my heater's electronics section looks like this:
&lt;img src='/stuff/20100621f.jpg' alt='replacement' /&gt; 
New PSU, PLL generator, U coil detector (wrapped in RED). Heater is working BAD. I need to rethink it again. In resonant mode it can drain lots of kilowats and blow everything arround. I can not control it. :(</description>

					<description>i am so sorry to say this man, but i have tried it for several hours once again and still couldnt make it, i think somehting was wrong with the installing, just couldnt view the components, but the pcb and schematic were ok to view. 

most of us, eletronics diy enthusiasts, are newbies in electronics and dont know how the programs work and need pics for the instructions, we are always confused all times, when we have to dive into deepness of ur professional skills, bro.

man, would you help us, ur fans, to attach another .RAR file consisted of pics of completed setup; the complicated parts and what a complete setup look like, and a notepad file of components. 

not all of us, newbies, can do it in eagle, bro, like me couldnt do it too, man

please help, bro, please save me from the frustrating condition</description>

					<description>im sorry to say this, but i couldnt do that, new to this program, just installed it and knowing nothing to operate it thought it seemed easy, i think something went wrong with the installation, errors all the time when installing. 

like most ofthe others induction heaters enthusiasts, i am new to electronics too, bro. so i need to gather the components first before beginning to understand the pcb working. would you help us, the amateurs of electronics to attach another .RAR file to download consisted of the list of the components in notepad file, and the pictures of the completepcb, se we can learn how the components linked together, how would it be if we made a success building one like yours. please, bro, we, the amateur enthusiasts, always get confused of how to do these cool stuffs you did, man

please help man, dont need to be super specific about the pics, just the pics u took when the pcb and the other complicated components like power supply, man</description>
