How to generate a short high power pulse?
Building a mini Marx Generator: Kind of like this http://www.electricstuff.co.uk/marxgen.htm Maybe triggered by a relay.
How to generate a square pulse at controlled voltage and time?
However, getting a square pulse at a controlled voltage and time will be more difficult. If you are willing to waste most of the energy, then a 3 kV clamp would work. You adjust the energy so that the time at the 3 kV clamp limit is the 10 µs you want. Possibly multiple ignition coils will need to be in parallel.
Can a single cap and resistor drive a circuit?
Depending on your definition of short, and close, a single cap and resistor can do the job: You can play with C1 and R1 to achieve the desired shape. Try using a 555 IC in the monostable configuration, with this circuit you will be able to drive small loads, e.g., LEDs and logic circuits.
What should be the length of a short pulse?
The pulse should be as short as possible (I’d say no longer than 10 µs). The shape of the pulse is not that important, but it should be reproducible and short and deliver about 30 mJ or more. And the whole thing should be as cheap as possible.
How is a power pulse generator connected to a generator?
It can be connected to the Power Pulse Generator by a jack plug on the end of the cable from the unit. You can buy an advanced version of this signal source here. Different ignition coils or transformers will have different resonant frequencies. Using this circuit allows the Ignition coils to be tuned and driven at their resonant frequency.
How does a pulse generator work in a X ray machine?
The signal generator circuit is housed in an independent unit with its own 9V battery. This can be connected to the main unit via a shielded cable allowing it to be operated from a safe distance. The high voltage output from the ignition coils is rectified using some large high voltage diodes (D2) designed for X-Ray machines.
Where can I find the pulse width control circuit?
This circuit can be found on the DIY Devices Page and is titled Signal Generator with Pulse Width Control. This circuit is housed inside a small hand held box with a 9V battery. It can be connected to the Power Pulse Generator by a jack plug on the end of the cable from the unit.
