the guy Posted January 8, 2010 Share Posted January 8, 2010 am i right in thinking that transformers can step up voltage to much higher levels? if so then what is the point in voltage multipliers? they are pretty complicated in comparison so surely it is alot simpler to use transformers?

tvp45 Posted January 8, 2010 Share Posted January 8, 2010 Transformers are fairly large, expensive, and heavy. It really depends on your application. Link to comment Share on other sites More sharing options...
insane_alien Posted January 8, 2010 Share Posted January 8, 2010 voltage multipliers supply a DC output. auch an output is not feasible with AC output of a transformer as you need very robust and likely large diodes to form a rectifier capable of handling the extreme voltages.

the guy Posted January 8, 2010 Author Share Posted January 8, 2010 if the input in a voltage multiplier was DC, would you need the diodes? Link to comment Share on other sites More sharing options...
insane_alien Posted January 8, 2010 Share Posted January 8, 2010 if the input to a voltage multiplier was DC then it wouldn't work. Link to comment Share on other sites More sharing options...
the guy Posted January 8, 2010 Author Share Posted January 8, 2010 ok, whats the best way to greatly increase dc voltage? Link to comment Share on other sites More sharing options...
insane_alien Posted January 8, 2010 Share Posted January 8, 2010 depends on the application. its like saying whats the best way to drive. its going to vary depending on what the desired goal is. what sort of load will it be required to cope with , what variance in the voltage is acceptable, how restrictive are costs etc etc. Link to comment Share on other sites More sharing options...
the guy Posted January 8, 2010 Author Share Posted January 8, 2010 well basically i want to make an air ionizer but with a dc power supply Link to comment Share on other sites More sharing options...
Externet Posted January 8, 2010 Share Posted January 8, 2010 What is your DC supply voltage available, what is the ionizer output DC voltage desired, at what current and what polarity ( negative ions or positive ions ) ? Link to comment Share on other sites More sharing options...
