AC-DC Power Supply: How It Works and Its Applications
Autor： Módulo de potencia ZYG Time： 2023-4-26
Introduction
AC-DC power supplies are an essential part of modern electronic devices, ranging from small portable gadgets to large industrial equipment. These power supplies convert the AC (alternating current) voltage from the mains supply to a DC (direct current) voltage that is required by the electronic device. This article aims to explain the working principle of AC-DC power supplies and their applications.
Working Principle
AC-DC power supplies typically consist of two stages: a rectifier stage and a filter stage. The rectifier stage converts the AC voltage to a pulsating DC voltage, while the filter stage smoothes out the pulsations to produce a steady DC voltage.
The rectifier stage can be implemented using different types of circuits, such as half-wave rectifiers, full-wave rectifiers, or bridge rectifiers. In a half-wave rectifier circuit, only one half of the AC waveform is converted to DC, while the other half is discarded. In a full-wave rectifier circuit, both halves of the AC waveform are converted to DC, resulting in a higher efficiency. A bridge rectifier circuit is similar to a full-wave rectifier, but it uses four diodes instead of two.
The output of the rectifier stage is a pulsating DC voltage, which still contains some AC components. The filter stage consists of a capacitor and/or an inductor that smooths out the pulsations and reduces the AC components. The capacitor stores charge when the voltage is high and releases it when the voltage is low, resulting in a more constant DC voltage. The inductor resists changes in current flow, further reducing the AC components.
Applications
AC-DC power supplies are used in a wide variety of applications, from consumer electronics to industrial machinery. Some common applications include:
1. Computers and peripherals: AC-DC power supplies are used to convert the mains voltage to the DC voltages required by the computer and its peripherals, such as the monitor and printer.
2. Mobile devices: Small and portable electronic devices, such as smartphones and tablets, use AC-DC power supplies to charge their batteries.
3. LED lighting: LED lights require a constant DC voltage to operate, which is provided by AC-DC power supplies.
4. Industrial equipment: Heavy machinery, such as CNC machines and robots, use AC-DC power supplies to power their motors and control systems.
5. Medical devices: AC-DC power supplies are used in medical equipment, such as MRI machines and ultrasound scanners.
Conclusion
AC-DC power supplies are an essential part of modern electronics, converting the AC voltage from the mains supply to the DC voltage required by electronic devices. The working principle of AC-DC power supplies involves two stages: a rectifier stage and a filter stage. AC-DC power supplies have a wide range of applications, from consumer electronics to industrial machinery and medical equipment.

Convertidor AC-DC: conversión de corriente alterna a corriente continua
AC-DC converters are electronic devices that convert alternating current (AC) to direct current (DC). They are commonly used in power supplies for electronic devices, such as computers, televisions, and mobile phones. The converter changes the AC input voltage to a DC output voltage that can be used to power these devices. The AC-DC converter operates by rectifying the AC input voltage to a pulsating DC voltage. This is achieved using a rectifier, which is typically a diode bridge. The rectifier allows current to flow in only one direction, effectively converting the AC voltage to a series of positive and negative voltage pulses. After rectification, the DC voltage still contains some ripple, or fluctuations in voltage. To remove this ripple, a...
