I am looking for a high current rating IGBT specifically high 'Maximum pulsed collector current'. It should be in order of 5kA. Are there IGBTs capable of carrying this high pulsed currents? Could anybody name few products which are suitable for this rating.
Thanx and regards

Hi,
I was trying to simulate a cascaded double stage 555 timer IC ckt. The motto was to get two voltage o/p displaced in time. But the voltage pulse at second stage output is vary less. I am using a 10 V battery as the source and the first output voltage pulse is around 9.6 V but the output...
Yes, Current 1,2 and 3 are current measuring devices during simulation. In my circuit also voltage is applied anode to cathode by Capacitors charged up to 500V. Thyristors dont have common point. Capacitors will be discharged one by one after each other.
Thanx for the reply. SO What components should i sue and how should i proceed towards it?

I am also ready to buy some components from the market to build the driving circuit.
The thyristor datasheet is this one:
**broken link removed**
the second thyristor should be fired about 3-5 millisecs after the first one and the third thyristor about 3-5 millisecond after the secons one. Its a one shot discharge so firing also needed of a single pulse.
HI! Sorry for the late reply. I was out of town for few days. I am ready for it now. The only problem is the micro-controller part. Lets see if we can do something about that. There are 3 numbers of capacitors being discharged using 3 thyristors so i need to trigger 3 thyrsitors for one shot...
Hi!
I am nt very familiar with electronics design. Just have some basic knowledge. For one of our projects to heat an alloy with capacitive discharge current being controlled by SCRs, i need to make a 3 stage time delay trigger circuit using 555 ics(or any other suggestions?). Could anyone...
Hi!
Thnx for the suggestion.
The output pulse i am getting now is of 4.5 V. I want the desired output pulse of 20 Volts. How can I arrange multiple of these 555IC circuit in series to get 20 V output?
Hi!
M new to Pspice.. (have to use it for a project). while simulating a simple 555 IC circuit in Pspice i am getting the following error msg. Could anyone tell me what should i do to resolve this?
Error Msg:

Thnx for the reply! Yeah I am very interested to do this... any help is appreciated. I have decided to use Thyristors instead of GTOs. So to fire these within milliseconds after each other which of the two methods is more suitable?
I am designing a capacitive discharge circuit to heat an alloy. The ckt is attached. I have to build this circuit in practical also for a project. I need to fire the thyristors in every branch once to discharge the capacitor. After the discharge time of milliseconds the other branch shoud be...
