CRD-02AD09N PFC drawings?

Found the CRD-02AD09N application note document and I would like to ask for the better readable drawings for Figure 35 to 37 referenced on page 37 of this document.

I am an freelancer electronics enthusiast and I would like to take a closer look at it in order to improve my simple PFC.

Has Cree / Wolfspeed published any other similar documents? If so, maybe I could get references to them as well.

I am very interested in using the C3M0065090J what I have, in my PFC controller, referenced also in this mentioned document.

In my existing project, based on an analog controller MC33262, Critical Conduction Mode Topology. At least I would be very, very grateful if I could find tips on how I can use the SiC MosFET together with this outdated MC33262 controller. In my previous solution, this controller has worked good at my design. PFC worked with minimum controller operating frequency at a maximum input voltage of 275V is 25kHz and the maximum controller frequency is 62kHz at a minimum input voltage of 185V, I use STmicroelectronics STP13NM60N MosFET and BYC8-600 diode in PFC output but because Si-MosFETs with good performance are not very available I would like to modify this existing design to SiC. C3M0065090J seems very suitable for improving my PFC performance. My current PFC solution has a power of about 400-450W, if I could double it in the SiC solution, I would be very happy as an amateur designer. In this current, justified circuit, I use STmicroelectronics STP13NM60N MosFET.

I have some C3M0065090J SiC MosFETs, and probably suitable gate drivers from Skyworks - specifically the SI8271DB that I would like to use. But I feel a little stuck alone in connecting them together - how do I do that? Maybe Cree/Wolfspeed have published any application note for tips on using a SiC transistor in these kind of projects? However, this is my first SiC project and I would be grateful if I could get tips.

Thanks for taking the time.
