  • This invention relates to systems and methods to increase electric voltage for residential, commercial, and industrial loads. [0006] 2. Description of the Related Art
  • Electricity for residential and industrial use is typically generated at an electric power generating station, and sent through transmission lines in an electricity grid to a distribution system, which carries the electricity to the consumer.
  • electric power supply has not kept up with demand, often resulting in brownouts.
  • a brownout is a drop in voltage in the electrical power supply, often resulting in dimming of lighting when the voltage sags. Brownout voltages sometimes drop enough to cause appliances or equipment to stop operating. Such appliances or equipment may sustain permanent damage as a result of the low voltage condition.
  • a brownout may be caused by (1) inadequate power generation, (2) insufficient power transmission capacity, and/or (3) insufficient power distribution capacity. Inadequate power generation and insufficient power transmission are easier to remedy than insufficient power distribution capacity. Both power generation demand and power transmission capacity can be calculated and fulfilled comparatively easily within fiscal budgets.
  • the main obstacle to providing sufficient power to consumers is insufficient power distribution capacity.
  • the need for power distribution capacity cannot be easily planned for or economically implemented.
  • the power distribution infrastructure will be increasingly strained or overloaded by the additional loads placed on it.
  • the distribution problems can often be attributed to copper losses within the cabling that forms the distribution infrastructure.
  • a transformer transfers electrical energy from one circuit to another through inductively coupled conductors.
  • a varying current in the first or primary windings creates a varying magnetic flux in the transformer's core, and thus a varying magnetic field through the secondary windings. If a load is connected to the secondary, an electric current will flow in the secondary windings and electrical energy will be transferred from the primary circuit through the transformer to the load.
  • the ratio of the transformer is the number of turns secondary windings to the number of turns in the primary windings.

Abstract

L'invention concerne un système et un procédé permettant d'augmenter et de maintenir une tension. Des enroulements secondaires d'un transformateur sont connectés à la ligne d'entrée chaude et la ligne de sortie chaude, et ne sont pas commutés. Les enroulements secondaires peuvent être en série pour du 220/230 Vrms, et en parallèle pour du 120/127 Vrms. En variante, le transformateur peut être d'un seul type de tension spécifiquement pour 230 V, 120 V, ou toute autre plage de tensions. Un microprocesseur mesure la tension entrante et commande un commutateur électronique du côté enroulements primaires du transformateur pour court-circuiter les enroulements primaires lorsque le transformateur n'est pas nécessaire. Lorsqu'une amplification de tension est nécessaire, le commutateur peut être commandé pour connecter les enroulements primaires au neutre. Lorsque les enroulements primaires sont commutés au neutre, la tension secondaire s'ajoute à la tension alternative de ligne entrante. Il peut y avoir de multiples prises sur les enroulements primaires choisies par le microprocesseur pour fournir différents niveaux d'amplification à différents niveaux de tension d'entrée. La tension amplifiée peut être maintenue à des niveaux prédéterminés en se basant sur le rapport de transformation du transformateur. Il existe plusieurs modes de réalisation de commutateurs électroniques comprenant, non exclusivement, un circuit en pont de diode conjointement avec un dispositif IGBT. Des transformateurs avec différents courants nominaux et/ou différents rapports de transformation peuvent être connectés de façon amovible avec le système.
