Problems with this approach are inspiron 9200 service manual that with the higher voltage, peaks currents can be much higher than with normal designs and some means may be needed (e.g., series inductor) to limit this.
The actual output trigger pulse voltage can be controlled by the voltage on the trigger capacitor.I used the transistor in an inverting full-on/full-off switch configuration with a 1K resistor from my positive supply (5-12 VDC) to the collector lead.It is easy to reduce the energy to a level that is safe to repeat 60 times a second, but a usual cheap glass flashtube will not be especially bright - almost certainly dimmer than a halogen lamp consuming the same amount of power.This is sort of insurance to prevent any glitch pulses generated at the time the flash is triggered from feeding back to the logic.The problem is likely to be that you are exceeding the ripple current rating of the caps.I believe ILC used to provide these tubes on the open market (may still be) through Edmund Scientific, but they were too difficult for the general hobbyists and the market was zilch.Depending on the circuit, the required voltage rating may be anywhere from the peak of the AC waveform to the maximum output voltage of the circuit (both with a safety factor).However, both the peak intensity and the flash duration will increase with a larger capacitor.Below this voltage (when IL1 turns off there is essentially no discharge path other than the very small leakage of C1 and.The charge is monitored by the PWM through a couple of divider resistors.Design of Small Strobes, here are some general guidelines for the design of a small (5-20 W-s) battery or line operated strobe.This also applies to the use of alternative power sources with the following caveats: When using a 12V to 115 VAC inverter to provide the input to voltage multiplier circuits, cheap units produce a squarewave output with 115 V peak (since the RMS and peak.
This may result in excessive heat dissipation in the capacitor.

So, still operating on the assumption that it's a capacitive effect, we used the anode connection instead.
Include a surge limiting resistor of about 22 ohms in the common as well as a current limiting resistor in the output (before the energy storage capacitor) to allow the flashlamp arc to quench (e.g., ohms).
