{"id":358,"count":4,"description":"<strong>Power supplies: a comprehensive overview<\/strong>\nPower supplies are <strong>essential tools for powering electrical equipment<\/strong>; below is a general overview of these instruments.\n\n<strong>Power supplies: what they are<\/strong>\n<a href=\"https:\/\/it.wikipedia.org\/wiki\/Alimentatore_elettrico\"><strong>Power supplies<\/strong><\/a> are electrical devices that <strong>provide energy to electrical equipment<\/strong> by adapting the current flow from a main supply source. In this way, <strong>reliable power<\/strong> is provided to machinery, computers, and other electronic instruments. Power supplies <strong>can be part of the structure of the device<\/strong> they are intended to operate, <strong>or they can be stand-alone units<\/strong>. The latter must be connected between the mains outlet and the device to be operated.   \n\nGenerally, power supplies <strong>consist <\/strong>of a <strong>rectifier and a filter<\/strong>, which are tasked with providing a constant DC output voltage.\n\nThere are different types of power supplies with specific properties, but they all share a common characteristic: <strong>efficiency<\/strong>. This represents the <strong>amount of power<\/strong> actually <strong>supplied<\/strong> <strong>to the internal circuits<\/strong>, <strong>divided by the amount of power absorbed<\/strong> from the mains supply. \n\n<strong>Power supplies: function and components <\/strong>\n<strong>Power supplies<\/strong> <strong>convert alternating current<\/strong> from the electrical grid <strong>into direct current<\/strong> by lowering the voltage so that the device can be powered correctly.\n\n<strong>Depending on the operating principle<\/strong>, power supplies are divided into two categories:\n\n \t<strong>linear power supplies<\/strong>: provide one or more stabilized and constant DC voltages, independently of variations in the mains voltage;\n \t<strong>switching power supplies<\/strong>: stabilize mains electricity to produce a clean, stable, and efficient output voltage. Unlike linear power supplies, they transmit energy instantaneously. \n\n<strong>Each power supply<\/strong> consists of a filter, a stabilizer, and a regulator. Thanks to these <strong>essential components<\/strong>, the <strong>correct operation of the power supplies is guaranteed<\/strong>. \n\n \t<strong>filter: <\/strong>transforms the output voltage of the rectifier into a DC voltage that is as linear as possible;\n \t<strong>stabilizer:<\/strong> ensures that the output voltage has a fixed value, even if the input voltage undergoes variations;\n \t<strong>regulator: <\/strong>helps maintain the output voltage at a given value; unlike the stabilizer, it controls its behavior when supply voltage variations occur.\n\n<strong>Types of power supplies<\/strong> <strong>and sectors of use<\/strong>\nPower supplies are <strong>distinguished into different types<\/strong>, and each power supply has a different use. In general, <strong>four categories<\/strong> are identified: \n\n \t<strong>AC\/DC power supplies: <\/strong>transform alternating current from the electrical grid into direct current and regulate the voltage according to the needs of the device to be powered;\n \t<strong>DC\/DC power supplies<\/strong>: modify the input voltage and, if necessary, can modify the waveform;\n \t<strong>AC\/AC power supplies<\/strong>: are used in very specific cases. They allow for the lowering of the mains voltage; \n \t<strong>laboratory power supplies: <\/strong>offer the possibility to modify various current parameters. For this reason, they are used to test electrical equipment. \n\nDepending on their use, power supplies find <strong>application in multiple sectors<\/strong>. Among the main ones, we find: \n\n \tmarine and offshore;\n \tautomotive;\n \tmachine and plant construction;\n \telectrical wiring;\n \tmaintenance;\n \tindustrial production;\n \tmilitary and defense.\n","link":"https:\/\/sensorline.biz\/en\/power-supplies\/","name":"Power Supplies","slug":"power-supplies","taxonomy":"category","parent":0,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/sensorline.biz\/en\/wp-json\/wp\/v2\/categories\/358","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sensorline.biz\/en\/wp-json\/wp\/v2\/categories"}],"about":[{"href":"https:\/\/sensorline.biz\/en\/wp-json\/wp\/v2\/taxonomies\/category"}],"wp:post_type":[{"href":"https:\/\/sensorline.biz\/en\/wp-json\/wp\/v2\/posts?categories=358"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
