if i take a small transformer meant to be used at 120v:9v 60hz, and discharge a 360v 100uf capacitor (or similar) into the 9v winding, will i get a high voltage pulse on the 120v winding?
You just described a frequently-used principle. Don't tase me, bro!
Yes, and you can shock your friends. I use to do this all the time. BTW this is how the first stage of a tazer works, after they get it up to about 10,000V they switch over to voltage doubler circuit to push it on up.
Only at UF(which I am a proud student). I suppose you would as you have at that instant a rapidly changing magnetic field in the secondary winding, but it might occur so quickly or so violently that it may be un-noticable.
You sure will, as everyone else has said. An old fashioned way of generating that voltage in a more constant fasion is to get ahold of an old electromagnetic buzzer. You might even find one in a hardware store. Put the buzzer in series with a battery and the low voltage side of the transformer, and turn it on. The buzzer makes and breaks the circuit by pulling the armature towards an electromagnet when power is applied. The Armature is basically configured as a switch, when the armature is pulled to a certain point, the switch opens and the magnetic field turns off. When the armature springs back, it makes contact again and the process repeats. This switching on and off generates pulses to the transformer at a steady rate, and the HV pulses are seen at the other side of the transformer. You dont even need that capacitor. NOW LISTEN, THIS CAN BE DANGEROUS! The HV Pulses can shock you. DONT TRY THIS AT HOME!!! BE CAREFUL !!
Yes.roughly 4.8kV .for about a millisecond at about 10 microampsThe only problem with the design is the secondary insulation on the transformer may not be of the correct insulation class to provide the shielding required. It takes quite a bit of modification to the 90degreeC insulation for a 600volt class to get that up to the 4.8kV classAlso since your going for this type of system might i recommend you avoid holding this in the palm of you hand as well.Well I knew you wouldn't do that ,i was just kidding around.you could always rob the igniter off an outdoor grille ,the capacitive discharge from them is about the same.From the E
