Poor Simulation results compared to LTspice - possible improvement?

@KSKelvin

it is uncertain whether they can generate an “exactly same” profile to match every simulation point.

Thanks for your answer, I read ‘trtol2’ as ‘trtol’ and got confused!

For your information: In this particular case (all devices are almost perfectly ideal) PLECS shows the same losses as SPICE/QSPICE. The picture above is generated in 233ms, so there is some room for improvement in all SPICEs :–)
