how does an oscilator affect the outcome of a transformer
You do get an alternating waveform, but not necessarily the same wave which you put in. A sine wave is the only waveform which retains its shape when transformed. All other waveforms will have some sort of distortion on the secondary.Im assuming you get a quasi-AC waveform out of the transformer.
You could use a bridge, but for your purposes, I think a single diode (half-wave rectifier) will do.Do they then use a bridge rectifier
well... if you want to charge the cap at 400V then it shold ve rated more than 400V......like 500 or 450 of 600.....depends......
you might destroy it, it might blow and overheat if you charge it at its full rated voltage.
you can use a simle oscilator and a transformer......and a rectifier after the transformer and maybe a voltage stabilizer with some zenners.
beczuse the cap has a small value......it will charge quite fast at a not so high current.
you can make a 555 oscilaor and use transformer from an adaptor. connect the output of the 555, of course you should use a transistor to drive the transformer, to the 6V output at the transformer. then at the 220V part of the trnaformer you can get around 350-450V....i used a trnasformer once and got around 385V....wich is quite colse to 400.
