    Anyone having experience in selecting a suitable Core ?

    Hello, I want to add a Core in a single coil, in order to increase magnetic field strength. I have posted LTspice simulation of coil's current flow in 1mS. If inductance of coil is 5uH & it allows 1kA current rising per Microsecond, after adding core in coil, Inductance when measured of coil...

    A simple dI/dt confusion, Anyone like to try & solve it ?

    Julie has posted it on '1st page 1st photo'. Thank you

    A simple dI/dt confusion, Anyone like to try & solve it ?

    Which kind resistor I can use ?? Like high wattage rating Which won't blow up !

    Although, I was thinking of putting those capacitors on copper busbar. But Maybe wire resistance will be help ?? Should I use busbar?

    How to do that ?? Maybe wire resistance will be enough ?? Although, I was thinking of putting those capacitors on copper busbar.

    I am very far from actually running this circuit, But yes I will take necessary precautions mentioned by you. More importantly, I will give this work to a professional E.E who lives near me to do this experiment. Thank you! 1601893613 No, I meant 10 capacitors in parallel 1601893679 & about...

    Thank you for valuable information! According to datasheet maximum peak current of single pulse is specified with 1000A per component. I Am using 10 in parallel

    A simple dI/dt confusion, Anyone like to try & solve it ?

    Ok, I will try. But please confirm that I can do what I am doing. Since resistance of coil is very low. Can It create sparks in capacitors? In order to get 1uH, Can I use 150mm wire ? So what is dI/dt of above circuit?? do i need to worry about 1890A/uS rise time??

    A simple dI/dt confusion, Anyone like to try & solve it ?

    If you do try it with above specs Please send me that file also, since What I want is that or anything close to it. Can I use this SCR - VS-ST330C16L Can I use this circuit without adding any resistor? 1601815994 Ok, I will try. But please confirm that I can do what I am doing. Simce...

    Ok I will try, I never used LTspice. Can you please try with these specs 945v 400uf 1uH Coil resistance 1milli Ohm Total Discharge time 100uS

    A simple dI/dt confusion, Anyone like to try & solve it ?

    According to calculation : - 1uH coil is giving me 50A/uS for 100uS, If I use 4uH coil, it will give me 12.5A/uS for 400uS What I am trying to ask specifically is : - Will total time get increased by 4x ? Or It will only take extra 4uS for current to reach 50A, then for the rest of the time -...

    Please solve this SCR Current rating confusion!

    If SCR has 9000amps at 50hz non-repetitive current rating. What will be it's non-repetitive current rating for 35uS ?? Or Can we use this SCR for 3600amps / uS for 35uS ?

    Please help me with this Capacitor, SCR, low resistance coil problem!!

    I want to discharge capacitor in micro seconds, In order to to that I used very low resistance coil but When capacitor is discharged, SCR kinda blow up, meaning the positive & negative got connected together because of low resistance. What can we place in negative terminal to make sure that...
