can anyone tell me what is wrong with this circuit? Answered
i keep on burning my 555 each time. checked the circuit intallations more than ten times.
voltage using is 12v from a car battery.
however i am using irfp 450. i don't think that this is a problem.
my ammeter say 5 amps of current passing but no ark to the transformer.
first i thought that the transformer was not good. so i changed it. problem was still not solved.
then i thought that the winding was not goof. i rewound it but no success.
the mosfet just get hot.
so i think i will bring my driver to school monday so that i can know if the circuit works.
i removed the mosfet and put a led instead i also change to capacitor with a 10uf cap. the led blinks. therefore the problem is not with the circuit if the led blink.
what can the problem be. i used different kind of mosfets also. still not getting the arcs.
