A New PI Controller Scheme for a Class D Parallel Resonant Converter

https://doi.org/10.58571/CNCA.AMCA.2025.057

Resumen: In this paper, the modeling problem and the structural analysis from a control perspective of a Class D Parallel Resonant Converter are addressed. It is shown that the model of the converter can be written as a Port-Controlled Hamiltonian system. In addition, from the structural analysis of this model, it is formally proved that the control input of the device is given by the overlap of the two duty cycles that control the two switches included in the device. To illustrate the validity of this assertion, a classical PI controller is numerically implemented showing that manipulation of this variable leads to the achievement of a control objective.
