Générateur électriquethumb|Un générateur General Electric Un générateur électrique est un dispositif permettant de produire de l'énergie électrique à partir d'une autre forme d'énergie. Par opposition, un appareil qui consomme de l'énergie électrique s'appelle un récepteur électrique. Un générateur réel peut se modéliser de deux manières différentes : un générateur idéal de tension avec une résistance en série ; un générateur idéal de courant avec une résistance montée en parallèle. vignette|upright=.
Energy developmentEnergy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.
Rooftop solar powerA rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories. Rooftop mounted systems are small compared to utility-scale solar ground-mounted photovoltaic power stations with capacities in the megawatt range, hence being a form of distributed generation.
Solar vehicleA solar vehicle or solar electric vehicle is an electric vehicle powered completely or significantly by direct solar energy. Usually, photovoltaic (PV) cells contained in solar panels convert the sun's energy directly into electric energy. The term "solar vehicle" usually implies that solar energy is used to power all or part of a vehicle's propulsion. Solar power may also be used to provide power for communications or controls or other auxiliary functions.
Système d'alimentation autonomevignette|320x320px| Schéma d'un système hybride Un système d'alimentation autonome (SAA, ou ), ou plus précisément un système d'alimentation électrique autonome également connu sous le nom d'alimentation électrique en zone éloignée, est un système électrique hors réseau pour les emplacements dépourvus de réseau de distribution d'électricité. Les SAA typiques incluent une ou plusieurs méthodes de production d'électricité, de stockage d'énergie et de régulation.
Panneau photovoltaïque thermiqueUn panneau photovoltaïque thermique (PV-T), ou panneau solaire hybride, ou encore panneau aérovoltaïque est un dispositif conçu à la fois pour produire de l'électricité photovoltaïque et pour recueillir l'énergie thermique provenant du Soleil.
Dissipateur thermiqueUn dissipateur thermique est un dispositif destiné à évacuer la chaleur résultante de l'effet Joule dans un élément semi-conducteur d'électronique de puissance. Il s'agit de dispositifs généralement munis d'ailettes, qui doivent de préférence être montées verticalement pour faciliter le refroidissement par convection.
Electric power conversionIn all fields of electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical or electro-mechanical device for converting electrical energy. A power converter can convert alternating current (AC) into direct current (DC) and vice versa; change the voltage or frequency of the current or do some combination of these. The power converter can be as simple as a transformer or it can be a far more complex system, such as a resonant converter.
Power semiconductor deviceA power semiconductor device is a semiconductor device used as a switch or rectifier in power electronics (for example in a switch-mode power supply). Such a device is also called a power device or, when used in an integrated circuit, a power IC. A power semiconductor device is usually used in "commutation mode" (i.e., it is either on or off), and therefore has a design optimized for such usage; it should usually not be used in linear operation. Linear power circuits are widespread as voltage regulators, audio amplifiers, and radio frequency amplifiers.
Voltage converterA voltage converter is an electric power converter which changes the voltage of an electrical power source. It may be combined with other components to create a power supply. AC voltage conversion uses a transformer. Conversion from one DC voltage to another requires electronic circuitry (electromechanical equipment was required before the development of semiconductor electronics), like a DC-DC converter. Mains power (called household current in the US) is universally AC.
