We know that the main use of a rectifier is to convert AC current into DC current. To perform this function, the rectifier consists of semiconductor diodes.
There are different types of bridges such as half-wave, full-wave and full-wave bridges. Before we understand the use of rectifiers,
What is a Rectifier?
A rectifier is an electrical component that converts alternating current (AC) to direct current (DC). The regulator is similar to a one-way valve that allows electricity to flow in only one direction.
The process of converting AC current to DC current is known as rectification. The filter can take many physical forms such as solid-state diodes, vacuum tube diodes, mercury-arc valves, silicon-controlled filters, and various other silicon-based semiconductor converters After discussing what his rectifier which, some of its applications in the next section.
Applications and Uses of Rectifiers
- The main function of the rectifier is to obtain DC power from AC power. Rectifiers are used within the power supply of almost all electronic devices.
- The power supply usually has a regulator in series following the transformer, a smoothing filter, and possibly a voltage regulator. Below we have discussed some rectification applications.
- As we know, all electronic devices use DC power for operation. Using a rectifier on the power supply helps in converting from AC to DC power supply. Bridge filters are widely used for larger devices that can convert high AC voltage to low DC voltage.
- The use of a half-wave rectifier can help us achieve the desired dc voltage with step-down or step-up transformers. Full-wave rectifiers are also used to energize motors and leads that operate on DC voltages.
- Half wave rectifiers are used in soldering iron type circuits, and also in mosquito netting to drive lead to fumes Electric welding uses bridge rectifiers to provide a stable and polarized DC voltage.
- In AM radio, a half-wave rectifier is used as a detector because the output is an audio signal. The lower power of the current uses very little, which is a very difficult rectifier.
