Pulsed Power

1.Yes they are adjustable. You can use 0-125V and adjust it to 70V max.

2.They are fast enough and more than 25ms pulse.

3. Very cost effective.

Thanks

how much are we talking about in terms of cost...i requested a quote but it's taking long.

And their size and weight? i must put them in a 160x240x99mm box

First of all 25ms rise time is not fast relatively speaking. Did you mean ns? There are HV pulsers capable of kV switching at ns (yes, nano-seconds) rise times. Pulse rise time is largely dependent on transient current capability of the power supply being used and recovery of said power supply is based on pulse rep. rate. Are you pulsing in kHz... MHz?

Guest (previous and a GA) makes additional parameters that need to be known. The OP did not cite at what current. One uA would be easy. 100 amperes is another story. Frequency: what is desired? Is it fixed or externally controlled and by what parameter, like TTL?

I will not be driving a heavy load, so I'm looking at about 1.5A or less. Yes the driving signal is TTL

You're right, 25ms is not fast....I am aiming at generating 70V pulse with a 20V/us and fall time of 10V/us. I have chosen a power supply already but now the challenge is the switching circuit. I will have to trigger it with an FPGA. I tried a circuit with two transistors coupled together but the resulting pulse is delayed if my input's pulse width is at a couple of nano seconds.

any suggestions on a cheap solution for achieving a high voltage pulse with no delays and minimum overshoot? is a switch mode power supply suitable for this?
