The Full Toroidal Variator is the core element in many mechanical hybrid systems for vehicle applications like Kinetic Energy Recovery System and Infinitely Variable Transmission because it allows to manage the power transfer with continuous variation of the speed-ratio. In this paper the model of a Full Toroidal Variator is addressed using Power-Oriented Graphs (POG) that is an energy-based modeling technique. Modeling with POG allows to easily transform and reduce the model when some dynamics of the system go to zero. An extended and reduced POG model of the Full Toroidal Variator are given.

Abstract
The Full Toroidal Variator is the core element in many mechanical hybrid systems for vehicle applications like Kinetic Energy Recovery System and Infinitely Variable Transmission because it allows to manage the power transfer with continuous variation of the speed-ratio. In this paper the model of a Full Toroidal Variator is addressed using Power-Oriented Graphs (POG) that is an energy-based modeling technique. Modeling with POG allows to easily transform and reduce the model when some dynamics of the system go to zero. An extended and reduced POG model of the Full Toroidal Variator are given. Simulation results of the modeled system are shown.
