induction heater

Having played with a manually tuned induction heater a few times before I knew how tedious it could be to operate. For one thing the resonant frequency isn't constant, but varies with the work piece size and temperature of the tank components. If the operating frequency is used to regulate power, more time is spent watching a scope then the work piece. What I wanted was a driver that would automatically find the resonant frequency or regulate power on the fly. It would be nothing new actually, as this type of driver has been done before only with discretes (see links below). Tim William's IH is complicated as hell though, and I wasn't going for something that elaborate. So after many different versions I eventually got something which worked and was reasonably simple.

Simply put, this tool serves to heat up something made ​​of metal. using electromagnetic induction power.
try it!!! 

high voltage

FLYBACK ZVS DRIVER

(HIGH VOLTAGE ART)

 

   this is the schematic

component used :
My driver consisted of:

• 2 x IRF640's (RDS(on) of 0.18Ω
• 2 x 330nF capacitors in parallel with an extra 220nF added.
• 2 x 5W 470Ω resistors to pull the gates high.
• 2 x 12V 1W zener diodes.
• 2 x MUR160 fast diodes
• 2 x 1/8W 10K carbon film resistors
• A soon to be measured inductor      

what this circuit for?
this electronic circuit ,serves to raise the voltage. you can get a 40 thousand volt input 24 volt only. but the electronic circuit is dangerous. you must be really careful.
