Hi there kind people,
I have developed an inverter of my own, now I want to measure the efficiency of my inverter, the formula I used for my simulations circuit is : η=(rms(I(R1))*rms(I(R1)*R1)/avg(V(Vdc:+)*abs(I(Vdc))),
It might sound really naive but I am really confused on how to calculate my input current, I tried using a 1ohm 1W resistor to measure the input power and that only gave me around .635 amps.
Can anyone please enlighten me how I can measure the input current properly. Thanks in advance!!
P.s. the dc power supply I am using is 19v for now (will go upto 300 volt later) and it's showing me around .203 amps in the display of the dc power supply.
