The Dc resonant transformer

[Login to see usernames]

I did the first tests….

result two 1200 v 30 a transistors burned…

lot of questions….


The induced voltage is tremendously high in the secondary…

the primary has 360 turns and the secondary 220 turns the voltage in the secondary goes up to beyond than 500v applying less than 10v to the primary… but no power if loaded…

more to come…

which setup did you try? how much current in the primary?

this is the circuit i used…

the connections are exactly like the drawing of the 2 toroids… except the feedback winding in the primary core is only serving as a voltage limiting coil

The strange thing is the voltage at the secondary… too high

this?

Yes but on the right there are three cores together i ill do a picture…

today i bought more 8 transistors 1199v 30A

where do you put the 3 cores?
