I want to know how high voltage generator works
It contains an AC oscillator and a step up transformer. The AC oscillator converts the DC voltage to alternating current which the transformer then steps up to a high voltage. … Many people homebrew a similar device using an ignition coil from an older vehicle as the transformer. …
