Thanks for you so quick response. System like Cockcroft Walton voltage multiplier or is there some other type of arrangement?Yes.
All you need is about 7 or 8 diodes and a similar number of capacitors to do that!
See? It depends on how you feel about the word, "good".
Absolutely!System like Cockcroft Walton voltage multiplier?
I would love to hear from you on this as to why is it so bad or not good?Absolutely!
Can it really be done using boost converters? I was thinking of using them to achieve this but was not sure about it. Also, is it possible to use two of them in series instead of going for the doubler?You might be able to find a DC-DC converter on e-bay that will give you much higher efficiency. They're cheap and simple. A 50V output may be tough to find but if you could find one to efficiently boost to 24V, for instance, you'd only have to double that with an inefficient voltage doubler. Your overall efficiency would be much greater.
I don't know what the current will be when the voltage is raised to 50 V. Let's say it provides 1 mA, the time for charging will be 500 sec. In fact I am still looking for a practical way so I am yet to try anything. 6 V AC can be converted to DC using FW rectifier and a smoothing capacitor. After that I really don't know the next stage in the circuit. Is it possible to use two boost converters in series to get the required voltage? Also, can you provide a circuit which you designed?Is there any time limit to charge the cap? Have you tried a 6.3 V filament transformer or a 8 ohm output audio transformer on one coil? If you convert the 6 V AC to DC there are forms of buck converters or flyback converters that will give 50 V DC. Once made a flyback 3 V? to 120V. with 4.5 mH choke converted to transformer.
