Thank you steveelliott, i will try this. after that I will be back here.
one more problem is there with this program
while changing the above sine table in to float sintable [10]= {0.1,0.2,0.3,..............} etc it aslo reducing the switching frequency
Hi all
this the program that i have tried to generate sine wave PWM but has a problem when without adding the ADC
it works fine but when adding ADC read it lowers the switching frequency
const unsigned char sinetable[123]={0,6,13,19,25,32,38,44,51,57,63,69,75,81,88,93,99,105,111,117,122,128...
This transformer can deliver a power of
V x I x power factor = watts
if your load is a resistor, the power taken by the resistor = 5 x 0.5 x 1 = 2.5 watts (max)
Try to under stand average value of a time dependent quantity instead of average power
Then from that try to understand Instantaneous value,average and max. value of
current and voltage then u can calculate Average power
Over current is responsible for the burning of the winding.
DC supply I=V/R Current is by only the winding resistance
AC Supply I=V/Z Current is by winding resistance and Inductance Z=Sqrt. R^2+XL^2
So when applying DC supply, resistance only there to oppose the flow of...
Transformer core materials is always not be the same ( silicon steel with iron content high ). Then how the weight can compared ?.

Absolutely right BradtheRad

Efficiency % =Output/input * 100
Output + losses = Input power
losses = Copper loss +...
I think ."By monitoring the temperature and take a decision from that" It is not a good practice. Your transformer
insulation property will be lost. In smaller KVA rating transformers it is the actually happening with this test.
