Rectifier

A rectifier is a device that converts alternating current (AC) into direct current (DC) 1 . It can be used for power supply devices, detecting radio signals, etc. Rectifiers can be made from vacuum tubes, pilot tubes, solid-state silicon semiconductor diodes, mercury arcs, etc. In contrast, a device that converts direct current to alternating current is called an "inverter". The rectifier has two main functions: 1. to convert alternating current (AC) to direct current (DC), which is filtered and supplied to the load or to the inverter. 2. to provide charging voltage to the battery. 2. to provide charging voltage to the battery. Rectifiers are usually implemented using semiconductor diodes, which utilize the unidirectional conductivity of the PN junction to change AC current to DC 2 . Common semiconductor rectifiers include silicon rectifiers and selenium rectifiers, which have a wide range of voltages and currents and are suitable for use in various forms of rectified power supplies. In conclusion, rectifiers play an important role in power conversion and power management to ensure a stable supply of DC power in circuits.
