You should not expect each stage to double the voltage. From Wikipedia: "The no-load output voltage is twice the peak input voltage multiplied by the number of stages N", not input voltage x 2^N
I have disposable camera circuit, I bypassed diode and removed the flash capacitor so I get 500v 25khz output, I get around 1cm sparks with around 3-4 stages, if I add any more stages it doesn't get any better the spark stays around the same.
About 4 years ago I made a stun gun with 3 dollars ark lighter kit and the same voltage multiplier model you using there, I wanted to use an old crt flyback but was not good because of the size and the power to operate
this is probably the best video out there to explain how to make a voltage multiplier, just one or two questions, how much is the lowest and highest voltage i can supply this with before it malfunctions/ explodes?
@@MirkoPavleskiMK I finally found someone, teacher, can you teach me how to make an electric baton that can electrocute mice? The high-voltage generator I bought to make the discharge time is too short, less than 5 seconds, I want to make a 5000kv one that can kill mice at once
@@MirkoPavleskiMK I made a 10-stage voltage multiplier and I noticed that the output voltage seems to decrease right after stage 5. what do you think is the problem why voltage not increase in subsequent stages? thanks for the wonderful videos.
@@DIYPhil I think that in that case it is a matter of low power of the source of driving high voltage (HV transformer), actually the driver of the HF transformer. If the driver is self-made, try changing the number of turns on the primary of the HV transformer.
@@kruimels Yes, there are 2 measurements. 30kV/cm for non-ionised air and 11kV/cm for normal atmospheric pressure, temperature and humidity. So for most purposes you are right. I think the 30kV measurement is an ideal situation description. I have modified my comment :)
Although it's like yours, with 10 capacitors it doesn't work very well. I guess it's because of the source which is fed from a 3.7v 9800mAh battery. Is that true or not? If I use an AC flyback with a ZVS module (the frequency in empty 60KHz and in load 120KHz) is it good? The diodes are fast but will be able to handle the high frequency of the ZVS? What do you say?I'm afraid of burning the diodes because of the high frequency.
I commented on your other video, if the capacitors are rated for 20kv how can it output 200kv+. I made the same circuit as a child and learned the hard way that 3kv capacitors will blow themselves to smitheries at 20kv+ so how can the 20kv output 200kv?
I used hv source 1 circuit but when the input 12 v given from rectifier circuit the voltage get decrease to 3v ... Is then any alternative circuit ... And one more thing If the capacitor and diode ratings may reduce then the output will come or not..
I found a transformer on the internet as a source for the multiplier. it has 8 or 9kv 20ma 50-60 Hz at the output. it is good as a source if dont work my ac flyback from tv?
