Does Duty cycle related to output power directly?

[arvinfx]

As I know in boost convertor for provide target voltage we use this formula :
**broken link removed**

Dose this formula contain output power?
If no ,how we have to calculate output power?

 

[crutschow]

Output power is output voltage times output current (which depends upon the output load).

 

[arvinfx]

Sorry, But upon formula doesn't contain any amp!

This is precisely what Crutschow is telling you, that formula will not by itself calculate output power.

It is only a transfer ratio between the input and output voltage.

To obtain power, you must:

1) Algebraically solve for Vo as a function of D and Vi
2) Multiply that expression by your output load Il, assuming that your load is constant, and not another function of the output voltage

Thanks, What is formula for measure amp or power that we want ?

 

[ccurtis]

Yes, for pulsed output, average output power is a function of the output duty cycle and the peak output power, directly.

 

[fernando_g]

P = Vo^2/Rl if the load is a resistor

P = Vo *Il if the load is a constant current
