“…Numerous harmonic reduction techniques, such as those based on PWM rectifiers, are suggested in order to reduce the harmonic disturbance rate brought on by non-linear loads or power electronics linked to the grid (Lounnas et al, 2023;Dehnavi et al 2023;Hamida et al, 2023Hamida et al, , 2022aAlazrag et al, 2023;Othman et al 2023;Ardjal et al, 2023;Abdelmalek et al, 2021Abdelmalek et al, , 2018a. These PWM rectifiers provide a bi-directional power transfer, consume a current close to a sinusoid and can operate under a unit power factor.…”

This article introduces a novel and effective diagram based on direct instantaneous power control (DPC) of a PWM-controlled rectifier connected to the grid without a switching table. An optimum control vector of the PWM rectifier's input voltage, which depends on the switching states determined by a Petri nets controller, is adopted. This approach limits the instantaneous detection errors of reactive and active powers, maintains the DC bus voltage at a reference level, and ensures current close to a sinusoidal wave, guaranteeing operation at a unit power factor. The instantaneous tracking errors of active and reactive powers and the angular position of the voltage are used as input variables for the proposed controller, which then selects the best control vector for the converter based on the transition of a Petri net. The significant advantages of DPC based on Petri nets compared to traditional switching tables are that hysteresis comparators are not required, and the classical regulation of active and reactive powers is achieved in all sectors. Simulation and testing findings demonstrated excellent performance, supporting the viability of the suggested control approach using Petri nets.
