coupling factor
The used Solar transformer 6220-1A has a 2:1 turns ratio transformation at 1kHz. This ratio
will change with higher frequencies. At 100kHz the effective ratio is more like 16:1. EM Test
thinks the inter-winding capacitance results in a higher than anticipated drive voltage to
produce the +/-5V signal at the secondary.
Therefore the user has to adjust the transformer ratio of his transformer in the CN200N by
changing the Coupling Factor to approx. 10.7 in the setup shown in the upper figure. The
exact value must be measured during calibration.
