That particlar double break is just to isolate the power supply after charging. The output circuit is also isolated by a double-break which is enabled by the CPU only after certain conditions are met. Finally, the output is also enabled or disabled by a manual keylock switch.
The rep rate is...
Thanks for all of your responses. Cornell Dublier and United Chemi-Con both make an electrolytic cap designed for repetetive high energy pulses. However, the leakage is spec'd at 1XC in uA after 5 minutes. So I am looking at 300uA leakage, which means the dV/dt will be about 1V/sec after the 5...
Thanks for your input Skogsgurra. Using a 10M-ohm divider means the capacitor voltage would drop 5% after about 2 minutes. This would probably be acceptable but I will need input from our intended user first. I just wanted to know if anyone knew of another way to do it.
Just for clarification...
Hacksaw, that was a useless post. I might be able to forgive you since you're "mechanical". The bottom line is, I was asking for a suggestion to monitor capacitor charge, not a critique of my whole design. If I wanted that, I would have to describe the entire project in detail, which...
If by accuracy you mean the threshold of the indicator, I would specify it at about 95% (190V). The signal will simply be a logic "high" or "low" to the CPU. The purpose of the design is to provide a pulse of specified current and pulse width, in this case 40A for up to...
I am designing a current pulse generator, and need to come up with a way to indicate to the CPU when a 280uF capacitor bank is charged to 200V. The design involves switching the capacitor bank between the 200V supply (charging) and the output circuit (isolated). I am not aware of too many...
