In this article, we are studying the non-linear effects in a single-phase H-Bridge inverter. The PWM control is related to a current feedback control. We are proposing an analytical model, which is a piecewise linear map. The distinctive feature of this study lies in the investigation of the map's properties. This investigation allows for the analytical(More)
The main drawback of the discrete time models Width Modulation (DPWM), from the dynamic behavior point reported in the literature for predicting nonlinear phenomena of view. We give the different operating modes and their state in power electronic circuits is their complexity which makes space equations in a general form. Then for a specific mode their use(More)
This paper deals with the problem of synchronization of chaotic dynamical systems. We consider a drive-response type of synchronization via a scalar transmitted signal. Unlike most works we consider the presence of some unknown inputs in the drive system and that no knowledge about their nature is available. A reduced-order observer-based response system is(More)
By using a non linear discrete time model, this paper shows how to predict bifurcations in a two cells chopper and analyses the road to chaos. Equilibrium points and their stability are investigated in an analogical way to determine the nature of the bifurcations. The global behaviour is studied by using bifurcation diagrams showing collisions between fixed(More)
Pulse width modulation (PWM) current-mode single phase inverters are known to exhibit bifur-cations and chaos when parameters vary or if the gain of the proportional controller is arbitrarily increased. Our aim in this paper is to show, using control theory and numerical simulations, how to apply a method to stabilize the interesting periodic orbit for(More)
This paper proposes a comprehensive MATLAB Simulink simulator for photovoltaic (PV) system used for the battery charging application in isolated microgrid. It presents maximum power point tracking (MPPT) control of PV system using Incremental Conductance (IC) optimization algorithm. A dc-dc converter is used to assure the connection between the PV source(More)
