I need an convertor or something else to reduce the current in primary side LIKE SMPS(O/P LOAD CURRENT IS 12A BUT I/P CURRENT IS 2A(approx.values)).
I noted in SMPS the current taken on I/P side will be low when compared with the secondary side.
Like that I need an circuit to reduce the current on primary side.

I read an article in which they used XL4015 to boost the current.In this whats the relation between the O/P and I/P current.
 

Hi,

no useful information.

Show your circuit. Input voltage--> AC, DC, what voltage?

The main rule is: Input_power = ouput_power / efficiency.
