All,
I need help with a Don Smith LTspice sim I've been working on.
The problem is that it is showing a COP of 1.128
why don't you integrate from 5 to 6 ms. Starting at 0 s is before steady state has been reached.
EM,
I'm starting the integration at 4ms.
.tran 0 10.6m 4m
If I start at 0s I get a COP of 1.059
pin: INTEG(v(vs)*i(v1))=-13.0589 FROM 0 TO 0.0106
pout: INTEG(v(vout)*i(rl))=13.8418 FROM 0 TO 0.0106
cop: (pout/pin)=-1.05995
Edit1:
I think you misinterpreted what I was saying.
The efficiency greater than 100%
Yes I am delaying recording of data 40ms to overcome the initial power draw establishing a somewhat steady state condition.
I am trying to get the simulation back to realistic conditions.
Edit2:
In case anyone is interested, I figured this out.
Determining the input impedance and setting the Source series resistance equal to that value corrected the problem. It now show realistic results.
