building AC/DC charger........

Hello to all; I want to build a charger with these features; I have some ıdeas but İ couldn't complete toggeter I am waiting your suggestions;
thanks all:razz:

Input voltage 200...250VAC
Input frequency 40...60Hz
Input current 16A max
Output voltage 320...420VDC
Power factor >0.92
Efficiency >%85
Inrush current Limited by appropriate circuitry
Input fused Yes
Output ripple <100mVrms
Line and load regulation >±0.5%
Output protection Short circuit protection by self resetting electronic current limiter
Status led indicator Yes: Power OK / Fault
Isolation Input-chassis, input-output and output-chassis >500VAC
Mechanical Protection IP20
Operating Temperature -20...+50°C

Need to provide also the current output for this power supply... :grin:

aw.. I am sorry I forgot to add ; also output voltage can be adjustble with trimmer; and output current can be adjustbe with external 0-5 V DC analog input

So what's the maximum current out of the device?

i dont have any idea about this this features above was given us for a competition ; so i dont have any ideas to added on it

plzzz hellppp

Which kind of Battery you wanna charge by an output of 420V DC ....... :-(

maximum available Lead acid battery in the market is 12V battery that can be charged using 14VDC at the output of a charger. and the amperage can be set/designed by looking at the Ampere hour rating of the battery.

Different Batteries having Different Chemistry have different chargers usnig different Techniques to charge the specific battery. charger developed for one battery should not connected to charge the other battery with different chemistry. On overcharging the Li-ion batteries can Explode with huge blast and fire. while overcharged lead acid batteries can boiled and damaged.

so each battery must have its specific charger to charge it.

First you should tell which kind of battery ( its Chemistry, AH rating etc) you wanna charge and then develop the charger for that. the development/designing of the protection circuitry will be the next task on that charger.
