Series Load Resonant Converter

Hi,

I have a question about Series Load Resonant Converter example (https://www.mathworks.com/help/physmod/sps/examples/series-load-resonant-slr-converter.html).

In Continuous Conduction Mode 2 (CCM2), when turning on MOSFET I think there is ZVS and ZCS, but in the description of this example they say it's only ZVS. In the figure below it can be seen when FET is turned on it's current is zero, so shouldn't it be ZVS and ZCS? Maybe I don't understand something about ZVS and ZCS.

One more question, about this sentence:

"Observe the DC gain characteristic plot (0.5 Ohm traces), you will note that the experimental gain values are slightly shifted relative to the theoretical gain values."

How can I obtain experimental gain values?

Thank you,

Karla
