hi mike! Hope you had recovered by now ! It is working fine when i discharged each inverter connected to a capacitor by itself, but when i discharged both capacitors together, things just go haywire. I'm using one capacitor to act as an igniter to another. Really appreciate the help so far! Will...

yea, was working with the BXA-502 inverter and added resistor before the discharge capacitor. spoilt the circuit together with the power supply when the capacitor discharges.

hi, sorry but i have met with another problem. Quite a serious one. Inverter circuit works like a charm, a couple of times, including discharging via a capacitor. But the next day when i did the same thing, the discharge actually spoilt the inverter circuit together with the power supply. Is...

I bought a bxa-502 inverter by jkl component. it has an output of 650vrms with frequency between 70-90khz. I used a low speed/freq. capacitor for the voltage multiplier circuit but only able to achieve a mere 200vdc. how should I calculate the required high speed/freq capacitors and diodes...

hey Mike, really appreciate the help so far! With your suggestion, I managed to find an inverter by JKL components, part no. BXA-502, which is able to step up 5vdc to 650vrms. shld be able to step up to around 3kv after a series of voltage multiplier. Yes, we are actually looking this type of...

I checked the input to CCFL power supply, and the lowest I've seen is about 11vac. Will my current circuit be sufficient to supply that 11vac to kick start the CCFL ? Ah yes that will be interesting, but it is an air prototype at the moment, most likely won't be tested in a vacuum.

hi Mike ! really appreciate for the help. Yes, most of the time, the rectifiers died on the discharge. I will try out your solution and see if it improves the situation ! yea very much agree with you, but due to limited knowledge of electronics, this is the closest i ever come to ! =S

Questions on car ionizer circuit (a.k.a discharge circuit) hi all, I'm coming from a mechanical background and was tasked to carry on an electronic project. Attached is the schematic of the circuit, i tried looking up the net on the respective components and understand how each component...

Hi there, attached is the schematic. Hope it helps =D

I have been working on a circuit (similar to car ionizer circuit) for a pulsed plasma thruster, which is able to charged up a capacitor to voltage as high as 1.8kV. I have a diode which is able to block reverse voltage up to 2kV interfaced between the charging circuit and the discharged...
