Преобразователь переменного тока в постоянный: преобразование переменного тока в постоянный: An AC-DC converter, also known as a rectifier, is a device that converts alternating current (AC) to direct current (DC). This is necessary because many electronic devices, such as computers and televisions, require DC to function properly. AC-DC converters are used in a variety of applications, from household appliances to industrial machinery. The process of converting AC to DC involves several steps. First, the AC voltage is rectified, or converted to a pulsating DC voltage. This pulsating DC voltage is then filtered to remove any remaining AC components, resulting in a pure DC voltage. The resulting DC voltage can be used to power a wide range of electronic devices. There are several different types of AC-DC converters, each with its own advantages and disadvantages. One common type is the half-wave rectifier, which uses a single diode to rectify the AC voltage. This type of rectifier is simple and inexpensive, but it only allows half of the AC waveform to pass through, resulting in a low average DC voltage. Another type of AC-DC converter is the full-wave rectifier, which uses four diodes to rectify the AC voltage. This type of rectifier allows the full AC waveform to pass through, resulting in...
