Keep in mind the reason they use 110 volts and spark gaps is that 555 and MosFet devices are very easy to kill when subjected to high voltage or high current, well, just call it high power.
If you manage to run a current through the primary coil, it will cause a magnetic field which will...
That circuit looks an awful lot like a circuit for driving an LED using alternating current. The LED would rectify the small alternating current and the resistor would limit the current so as not to burn out the LED. The capacitor would couple the AC to allow enough current to flow to allow the...
Think of it this way. What is the easiest life for a capacitor? It would be having only pure DC at its inputs. 60 changes a second is more work than 50 changes a second. If you look at how much energy the device is exposed to , that would also be less. That would imply for the same level of...
20Khz is an audio frequency. Transformers that handle that frequency could be looked for at places such as Radio Shack.
The problem with using a transformer to raise the voltage level of a square wave is that you will loose the high frequency components of the square wave due to the action...
