Yes, I know what Toyota calls their PSD. Though, there is mentioning that PSD was assigned "CVT" designation for Toyota to be able to match Federal regulations and market transmission in the US. If you take simple look at PSD internals and compare it to any CVT internals, you will see that there is nothing in common and principles of operation are different. PSD is epicyclical gear set. More similar with that of a standard automatic transmission.
Peculiarly enough, they now added "shifting points" to PSD, mimicking a 6 speed automatic shifts. Allegedly, owners thought their transmissions were broken without shifting points.
This is old but very good course on PSD:
Have you noticed how the terms “rotation” and “revolution” are used? Those “power carriers” are sometimes affectionately referred to as “planets” and the motor in the center as “sun”. Knowing all that, it becomes clear why this PSD design has been officially named as a “Planetary-CVT”. It has absolutely nothing in common with the other type of CVT that utilizes a cone and a belt to transfer power, but it does feel like it is the same.
