hi
are you tested this smps by own?
is it good?
can i use ee55 core for 500 watt in your smps?
can i reaplace irfz44n mosfets with irfz42?
what about r1 to r6?
can you calculate R1 to R6 for irfz44n please?
thanks


Yes, he posted a pick of his finished psu.
Yes, he says it is good.
Yes you can use EE55.
Yes you can use IRFZ44
R1 to R6 are jumpers = 0 ohm resistors...
 
Input voltage compensation for car smps

I've finished the feedback but.... I'm thinking about.... what about the input voltage compensation? the voltage of the battery will decrease with the time, it will be a good idea to compensate this variations also. Anybody knows about this?

The voltage of the battery will be fluctuating nearly all the time. If you want to tackle this problem then the only way for this is to regulate the output by some kind of feedback mechanism. The currents at the input for a car smps would be too big to handle economically.
