A generalized method for the derivation of non-linear state-space models from circuit schematics

In this paper, the authors present an original solution to maximize the DC power collected in the case of a wireless power transfer (WPT) scenario. Using state-space model representation, the WPT System is considered as a feedback approach in order to maximize the amount of harvested energy. To do this, a global simulation is performed to show the importance of taking into account the propagation channel and the rectifier circuit aspects in the case of optimizing the waveform to increase the harvested energy. By using an optimized multisine signal with zero phase as the excitation, taking into account the characteristics of the channel and the physical contributions of the rectifier, we managed to obtain better output DC values compared to a single tone source or a multi-sine signal without optimization, with the same average power input.

“…White box modeling relies heavily on physics, and requires extensive knowledge on the circuit, from components datasheets to circuit schematics. Such modeling include Wave Digital Filters [1,2,3] and State-Space representations [4,5,6]. Black box modeling on the other hand is more concerned with reproducing a global input-output behavior, without necessarily capturing local phenomena taking place inside the system.…”

This paper addresses identification of nonlinear circuits for power-balanced virtual analog modeling and simulation. The proposed method combines a port-Hamiltonian system formulation with kernel-based methods to retrieve model laws from measurements. This combination allows for the estimated model to retain physical properties that are crucial for the accuracy of simulations, while representing a variety of nonlinear behaviors. As an illustration, the method is used to identify a nonlinear passive peaking EQ.
