Hello all.

If you are using MicroSim v 8.0 for your simulations, I would like to warn you
about an issue I noticed when simulating TC primary, secondary and
interactions.

Namely, the resonance frequencies displayed in the transient analysis were
WRONG! I reduced the circuit to one capacitor and one inductor: then it should
have been

f = 1/( 2 PI sqrt(L*C))

but MicroSim made a big error (5 - 10%) on the time scale: displayed frequency
was WRONG.

I had the option RELTOL set to 0.001 (the default). Setting RELTOL to 0.00001
made a very big change and displayed the CORRECT frequency. Therefore, check
your RELTOL and correct it accordingly to get consistent results.

Regards
