Nowadays, it is known that every action made with the aim of contributing to reverse the global warming is appreciated according to its intrinsic value. Through the effect of economies of scale, together, the little actions made elsewhere are significant. If each person or every family in any area uses solar energy in all its domestic activities, the damage due to energy consumption in the world will be very low. This paper presents the command of an autonomous single phase converter with shifted command used to stabilize the energy produce by the photovoltaic cells in regard of the normal condition of usage. This shifted command aids in modifying the characteristics of the output voltage, particularly the effective value of its fundamental without involving the continue voltage of its energy supply. In multiple applications, it can be used in the energy supply of sensible devices like non synchronous machines. When this is jointed to a pump, it can produce drinking water by a tangential ultrafiltration unit of water with a perforated fiber. When it is combined to the command of the static converter of Mc Murray Bedford which is constituted of a monostich and a dephaser, commanded by the mutual inductance in order to obtain of a tension too close.

Abstract
Nowadays, it is known that every action made with the aim of contributing to reverse the global warming is appreciated according to its intrinsic value. Through the effect of economies of scale, together, the little actions made elsewhere are significant. If each person or every family in any area uses solar energy in all its domestic activities, the damage due to energy consumption in the world will be very low. This paper presents the command of an autonomous single phase converter with shifted command used to stabilize the energy produce by the photovoltaic cells in regard of the normal condition of usage. This shifted command aids in modifying the characteristics of the output voltage, particularly the effective value of its fundamental without involving the continue voltage of its energy supply. In multiple applications, it can be used in the energy supply of sensible devices like non synchronous machines.

Abstract: (french)
Il est d'actualité et compris de tous qu'en cette période, chaque geste visant à contribuer à inverser le réchauffement climatique serait apprécié à sa juste valeur. Par effet d'économie d'échelle, la somme des petits gestes produirait forcément un résultat visible et appréciable. Si chaque individu ou chaque famille dans sa vie domestique courante s'appropriait l'énergie solaire, la marche énergétique du monde actuel sera certainement différente. Cet article présente la commande d'un onduleur autonome monophasé en pont, à commande décalée, destiné à la stabilisation de l'énergie produite par des cellules photovoltaïques en vue d'une utilisation dans les conditions nominales. Cette commande décalée permet de modifier les caractéristiques de la tension de sortie, en particulier la valeur efficace de son fondamental sans avoir à intervenir au niveau de la tension continue d'alimentation. A application multiple, on pourrait s'en servir par exemple dans l'alimentation des dispositifs sensibles tels que des machines asynchrones. Le couplage de ces dernières à des pompes pourra servir à alimenter une unité de filtration d'eau tangentielle à fibres creuses destinée à la production d'eau potable en zones reculées. Associé au circuit de commande du convertisseur statique de Mc Murray Bedford constitué d'un monostable, d'un astable et du circuit déphaseur, commandé par la mutuelle inductance pour une obtention d'une tension plus proche d'une sinusoïde, ses performances se trouvent améliorées.
