Hi,
I'm a bit confused.
I'm measuring the efficiency of my off-line 230 V flyback converter.
I sampled the mains voltage Vin which is a sinus wave.
I sampled the Input current flowing from the mains into the converter which is a non linear curve.
To evaluate the efficiency I need to evaluate the input power.
QUESTION:
Which of the following formulas should I use?
AVERAGE POWER
(1 / T) * integral from 0 to T {Vin (t) * Iin (t)} dt
RMS POWER
SQRT [(1 / T) * integral from 0 to T {Vin (t) ^2 * Iin (t) ^2} dt]
Thanks,
Enrico Migliore
