1.5 KW switching regulator

[FvM]

with the first equation I calculated Iav . it is 33A!!!!!!
is it correct?

I don't know which numbers you put in the calculation.

Hi
I think your calculations aren't proper .

I use 1500W for P(out) . 90% for Efficiency . and 50V for Vin . and the result is 33A .

 

[goldsmith]

Hi
How you calculated 33 A ? ( my mean is what is your formula ? can you show me , the steps of your design? thus i or the others can correct them .

the first formola in the blow link .

 

[goldsmith]

according to that formula it seems ok ,

I found a 3 winding transformer for LTSpice .Is it suitable for full bridge?. I want to change its parameters . how can I do it?

 

[meysaminter]

I went to " power sim " sait . and the sait's designer software's result is in attached file . the result is approximately similar to my design . but there are some difference such as L19 and C29 parts . is feedback proper for me? how aboat snubbers?

where is the Mastes of Power supplies?

 

[goldsmith]

Hi again
I'm a bit confused that what is your clear problem , right now ?

Goldsmith ,
I am tring to design a true circuit and then I simulate it for my project . and at final I will built this . my problemes with the circuit is in Previous comments.

 

[ronish]

please help me to design a linear power supply with output voltage of 2v to 25v dc. O

Hi All,

Hi please help me to design a linear power supply with output voltage 2v to 25v dc. Output power > or equal to 1.0 watt, output ripple < or eual to 50m V(peak to peak), Load regulation < or equal to 0.2%, Line regulation < or equal to 50mv/v

Thanks

Dear ronish
Hi
At first , it think you'd better to create new thread .
Anywhere , if you want linear regulators , try LDO what is good for your aim .
